Excellent antenna. Made significant DX contacts over the past nine months. Straight forward installation with very good support from Greyline.

I submitted a very positive review on the performance of my 20" flagpole but neglected to mention the high quality of the machining on the pieces and hardware. The pieces went together like a hand and glove.
Really appreciate the fine workmanship.

The 4’ extension arrived in a reasonable amount of time. Construction was excellent and assembled easily with my existing 24’ flagpole antenna. I have noticed improvement in reception and signal reports on the air, and look forward to continued experimenting on the air with this addition to my station.

Looks tremendous with Uk flag and works superb Highly recommended

I purchased the 24' flagpole antenna with 4' extension added later. The materials and construction are very good. Parts fit together very well. Antenna aside, this is a handsome flagpole with flag.
I had no expectations for 160 meters. I purchased the antenna to supplement my EFLW antennas for 40 and 80 meters. Initially all tuned well from 10 - 40 meters using an LDG RT-100 remote tuner, but unable to tune on 80 meters. I upgraded to a Chameleon CHA-URT-1500 1.5 KW remote tuner, but still unable to resonate on 80 meters. I added a Palomar 4:1 balun between the remote tuner and the antenna and now am able to tune antenna well on both 40 and 80 meters.
I have had impressive domestic and DX contacts on 10-40 meters so far. I am hoping that with a little more effort, I can eventually get DXCC on both 40 an 80 meters. Will keep you updated.

The build quality is excellent with tight tolerances. The buyer must be aware of a complete system antenna design. The includes environmental concerns of your QTH such as rain sprinkler system heat and lightning. Hear in California we have the extremes The website addresses some of the along with YouTube videos but the buyer has to put it all together.
Digging the 3 foot hole and finding the best pvc sleeve to use was a challenge along with compliance with QTH environmental concerns. I am happy with this purchase but there are challenges to deal with to make it work!

Superbly made quality antenna Recommended to all. Ordered 4ft extension out of curiosity Top class

Very sturdy with beautiful looks! First 3 hf contacts were Japan on 10 & 17 meters from Tucson, Az

I have two gray line antennas both with 4 foot extensions on them. I have a 24 foot with a 4 foot extension making 28 and a 20 foot with a 4 foot extension making 24. I have used both of these antennas and made contacts all over the world. I have an all continent award. I also have friendship awards on all bands 80 through 6 m I can tune 160 m as well. Only one contact on there because the band conditions have been poor not the antenna’s fault. These things are fabulous if you live in an HOA or an area where you just need a vertical Off Center fed dipole. Grayline , customer support and antenna quality are unsurpassed. These are aircraft quality, aluminum and hardware unmatchable in the regular antenna industry. These things are Support poles very lightweight. You can install it yourself but extremely thick sidewall tubing. This antenna will stand a lifetime of weather very inconspicuous and no problem working worldwide with only 100 W With an amplifier this thing would be unbeatable in contesting.

I'm very happy with the Greyline Flag pole antenna, easy to install and the shipping was fast with all the parts arriving at the same time.

I'm very happy with this antenna. It works wonderful and I couldn't be happier.

I originally installed a Greyline DX 24' Flagpole, in my covenant restricted area,
about 3.5 years ago and made several thousand OSOs. Super quality material, was
easy to install and performed better than expected from my noisy locale.

Due to some issues with the park I live in and some performance degradation, I decided to
refurb the installation with new feedline, balun (my tuner does not have a built-in balun)
choke and the ladder line. During the process, I found a frayed part of the internal
ladder line that look like it was chewed on and a few other minor issues (weather related)

Needless to say, it fired up first time with no issues (I followed the tips) and seeing
signals and S levels I haven't seen in awhile..

The DX Flagpole antennas are well worth the investment as they work extremely well,
made of highest quality materials that will last for a very long time.

Longest QSO was about 12,500 miles on FT8. Super awesome.

Looks great and works even better. I hear more stations on my regular nets than I normally do. I used stone papers for a rectangular wall around the flagpole which matches the house. A beautiful, wonderful, addition to my hoa property.

I was impressed with the quality of the antenna tubing used. It's not the normal aluminum used by the other manufacturers, but a precision machined tubing. It fit together tightly with the thick fiberglass insulating sections. Using the LDG-RT600 remote antenna tuner, it tuned very well on 40-6 (I don't use 160/80) as a ground-mounted 28 ft. vertical dipole and really captures the DX! My QSO and country count really started accelerating from where it was. I live on a small corner lot with no HOA, and have no real trees for antenna supports. I can now reach AUS and the South Pacific with ease from the East Coast of the USA. I had a special installation so it took me about 5 hours to install by myself (several trips to several hardware stores for clamps, all-thread and such). It was pretty much a 'remove and replace' with the old antenna. All-in-all, it was a worthwhile investment and upgrade, I love this thing!

I got HOA approval, even though they require white fiberglass flag poles. I explained that while it was a genuine flag pole, it was also an amateur radio antenna that provided emergency communications if needed. Living in hurricane country, that thought that was a very good thing to have in the hood.
As for the technical details of the antenna, speaking as one who has built their own flag pole antenna, this one is a great design and manufactured antenna. The machined parts and hardware are first rate! The performance is superb. I’m FT8 ing points easily 1000+ miles on 20w. (20 meters).

I’ve tried to include photos, but can’t seem to…..

I am providing my first impression report regarding my 24FT HOA antenna. Installation was easy once I was able to figure out the instructions. The twin lead spacers were missing so I inserted a section of PVC into the lower section to insulate the twin lead. I’m using an IC7300, MFJ 993brt remote tuner, Balun Design, Inc model 117t balun which takes coax as input and twin lead as output. I then feed it through an Array Solutions model AS309H arrestor which takes twin lead as both input and output. With the remote tuner: SWR readings are 1.2 in the cw portion of 40 meters and 1.5 in the ssb portion SWR readings are 1.1 all the way across 20 meters (my favorite band) SWR readings are 1.2 in the cw portion of 15 meters and 1.4 in the ssb portion I am a cw guy and have worked all over Europe and South America as well as New Zealand and am getting very good signal reports. Needless to say, I am very pleased with this antenna so far. It works way better than I expected I haven’t yet had to operate in windy or rainy conditions so there is more to learn.

I purchased the pole without the antenna and am very happy with the quality and ease of installation.

Added this to my 20ft flagpole for 160 m work. Able to make contacts, looking forward to up the power. Great flagpole!

What a wonderful Antenna I have made contacts in over 50 country's so far in less than three weeks easy to assemble and works.

I purchase a 20’ Flagpole antenna that also included the 4’ extension. I installed the flagpole the end of January here at my home in central Florida. The install was easy with only a couple of small issues that were easily resolved by just thinking things through. I installed the antenna in the back yard in the HOA and have not had any complaints.

The performance of the antenna has been very good. The SWR on most band has been =< 1.5 except the 12 meter band. The SWR is just under 2.0. The DX into Europe and Africa has been good. Have done a lot of FT4 and FT8 with good reports. SSB has been good with good signal reports depending on propagation. All of my contacts have been made on 70 – 100 watts. I am using a SGC 230 tuner mounted at the base of the antenna

Most of my contacts have been 10 MHz – 28 MHZ. I have done some work on 40 meters but not much. Not much of an night owl so I don’t get very much of a change to use the antenna on 40 – 160 meters. The SWR is on these bands is 1.0 – 1.3, so I would expect good performance if I had more power.

At this point in time the only negative I have to report is the flag. It has been flying on most days in 5 to 15 MPH winds. I have taken it down when we had higher winds had exceed the 15 MHP. I noticed this morning the flag was torn and shredded. I took the flag down and noticed the flag was made by Anley and it was manufactured in China. I wouldn’t expect a flag to be in this condition after 3 months. I had USA made flags last over a year flying in much stronger winds that this one.

I'm only giving a 4 because of the flag issue. I will reach out to Greyline to see what they have to say.

It has taken me a while to get it put together and up, but with the help and patience of two of my sons, my beautiful flag pole antenna is up and operational. I am still learning how to use my radio, just found out my microphone has an on/off switch for example. The install is complete but it is working already. I will send some pictures. I am thinking about a 4' extension for my 16' flagpole antenna. Does the extension go on the bottom? If it does, i may do that.

This is an antenna I wish I would have purchased sooner. We live in an HOA with a small lot and some restrictions on antenna placement and height. We had a small vertical antenna mounted to our fence, but had limited places to install grounds and could only put two in place along the fence line. We could only receive 40M, sometimes 20M, and both had to be tuned and adjusted at the antenna. This year, those bands began generating high SWR. I was able to determine the wiring and connections were all good but the antenna was failing and we would miss out on the new solar cycle. We ordered a 20' Greyline, without the flag mount options, along with an LDG 100W external tuner. Due to a backlog in supplies, it took many months to process my order, and when I paid with a credit card it was cancelled the following month because they could not ship it within 30 days to process my credit card. I called and they no longer had any 20' antenna packages to ship at that time, but they agreed to ship me a 24' for the same price without further delay. That was still not going to be visible from the street above my home which is an HOA requirement, so I agreed. After receiving the equipment and installing it, I was amazed. 40M, 20M, 12M, and 10M bands were all below 1.5 SWR. 30M was an impressive 1.1 SWR. Unfortunately, I could not tune 80M, 17M, or 15M due to high SWR. Quite possibly this is an issue with the LDG tuner. We have reached far away with this antenna, and my wife began using FT8 and collected QSOs with 29 countries on multiple bands within a week. I was able to reach Australia, which showed a distance of 10,000 miles. The antenna is in my back yard, close to my house and neighbors say they don't notice it. While I could have installed it in the front as a flagpole, I would have to re-rout all of my wiring to the front of the house. This is an impressive antenna. If I were to do this again, I would like to have purchased an already assembled ladder-line to PL-259 adaptor as assembling the provided kit proved somewhat challenging without a drill press which I no longer have after downsizing a few years ago, and having to modify the clamshell case so that it would fit over the PL-259 component. The RF-choke required weather proofing so I ended up purchasing 1-1/2" waterproofed shrink tube that seemed expensive for the length needed. In the end, it all worked well when connected. I fully recommend this antenna.

At the age of 79 was able to install the 20ft flagpole antenna without help, which surprised me. I installed solar lights above and below the flag and it's a beautiful sight at night. I attached the ladder line directly to the ground and long wire terminals on the MFJ tuner and it works perfectly. Very low SWR on all bands. In spite of poor band conditions I have been having a blast. Frankly, it tickles me to have my antenna sticking up in my front yard in plain site. My neighbors love it and the HOA is clueless. 73's, Kelly K4SLE

Band conditions have been tough running barefoot, but I have been working DX on 20 meters! DL, SM, YU, RU, ZS, TI all in a single morning with only 70 watts. In fact i have had so much fun being back on the air i have made the decision to replace my aging 30+ year old Kenwood with a new radio. I been pleased with the antenna and my neighbors have been pleased with the look of the flagpole.

I purchased two chokes, the coax to ladder line choke from the tuner output to the antenna ladder line and the coax to coax choke that I have installed at the radio. These work very nicely to tame noise. It's a worthwhile investment. The mini choke works better than the MFJ one that I originally was using.
