Best antenna I've ever had  Time owned: more than 12 months
I bought my GAP Eagle antenna new in 2008 and it has been my primary antenna ever since. I've worked the advertised bands from 10 up to 40 meters without any issues. I've also worked 30 meters with superb results although nothing in the docs mention 30 being available. I've also worked digital on 60 meters and even made one PSK contact on 80 meters! I'd not recommend using the Eagle on 80 but IMO this shows the quality and range of this antenna. If I were asked to suggest a good multi-band antenna for beginning hams, or for more seasoned hams looking for a relatively inexpensive antenna for digital work, the Gap Eagle would be it.

Works better than I expected  Time owned: 0 to 3 months
I found it to be very high quality, went together just as shown in the instructions. The instructions weren't Heathkit quality, but they were pretty darn good. Does a Heathkit reference date me? Good, I'm proud of it! I didn't have to make any tuning adjustments and have very good swr across the bands. Worked some great dx right out of the chute on 10 meters, one in Uraguay and one on Sakhalin Island east of Russia. It's a great antenna solution for limited space installations, I'm very happy with it. I also think it looks cool gleaming over my house.

Great for me  Time owned: more than 12 months
Bought it used in 1995. It is mounted 9 foot off the ground on a bolted down tripod.
I have worked the Antarctic more than once, New Zealand, Europe, Africa and the Middle East with 100w.
Of course I do have a large open area behind my home. Another person asked my help as his did not work well. Reason was it was surrounded by trees, houses and garages on a very small lot and only up about (9')high as mine but no space to get out.
You can't mount an antenna in a hole and expect it to work.
Also be reminded that the Gap Eagle cannot run with even a 600w amplifier on 40 meters.
I thought of using one but called first and was told it will damage the antenna.
But with 20 years and all those contacts I love it.

Fantastic Antenna  Time owned: 0 to 3 months
I never was a fan of verticals. But having just moved to Ft. Myers Fl and with limited space a vertical was the only alternative. Picked up a GAP Eagle and I'm truly amazed. I'm only running less than 100 Watts with a TS-480 and if I can hear it I can work it. I've worked every band from 40-10 and it really does the job. Amazing well engineered product. It's a series of vertical dipoles that are fed in the center of the mast. Well made and performs great.Highly recommend the antenna..

Easy install works well  Time owned: 0 to 3 months
Assembled and installed the gap eagle antenna in about three hours. It was fairly easy but directions are not great. They leave much to interpretation and the pictures are like scribbled by hand. Fortunately I have put up a lot of antennas and I was able to weave my way through them. Antenna went up easily with no issue. All bands tuned perfectly. Guess I got lucky. Antenna is larger than I first thought it would be and needs to be guyed. It toppled over on my tripod mount. Fortunately it wasn't damaged. Guyed it and it is still erect now. I am back on the air.

Works as advertised.  Time owned: 0 to 3 months
Just a short note to say that the GAP Eagle I purchased works fine. Built as per instructions and it fell within the 2:1 SWR ratings on all bands. In fact on all but 40 and 15 it is about 1.3:1 or better. Chris at GAP is very helpful and gave me a few things I could do to get them peaked using the tuning stubs so I will do that. On 40 the swr is 2:1 at 7Hhz but at 7.170 it is 1.5:1. I am going to measure the 40 stub cap and he said we can probably adjust that down with a different cap. All in all it has performed well and I will say the noise level on 40 has dropped about 2 s-units with no apparent degradation of the recieve signals. If there is any, the lower noise makes things much quieter and the signals are much more readable. Using 100 watts I have been able to work EU, Asia and VK/ZL and SA with no problems inspite of the poor band conditions I have experienced here in NM. I have it mounted just above the roof level about 15 feet high and have had excellent results.

It really seems to work best on 20-15 but havent really had good enough conditions to comment on 12-10. 40 works fine with a tuner for now.

Yeah, a 6 ele yagi at 75 feet would be better but I dont have room for that right now so this is a good substitute considering the situation.

If you need something small, easy to put up and aren't expecting monoband yagi performance this will work just fine. I imagine the other models may do better since they are longer but the landlord limited me so this is what I can do.

Great Antenna  Time owned: more than 12 months
Bought my GAP Eagle in 1998 and used it in FL. Have a very small lot and putting up a wire antenna at any respectable height was impossible. Installed it on a galvanized pipe next to house in my backyard and it was up 13 feet. The installation instructions were easy to follow and it went up on the pipe with no problem. It withstood many high wind events without a problem. The best part though was the QSO's I had with the Eagle. First used it with a Ten Tec Scout at 50W and couldn't believe the difference between using it and a inverted vee antenna that was too low to work dx- I could now actually work dx !!!!! Added a Kenwood TS 950 SD to the station and this made the dx experience even better. Had no problem tuning up the antenna on any of the bands with the internal tuner of the 950. Running without an amp I was able to break many pileups even on SSB. The Eagle received many compliments from other hams with my signal on all bands including 40 M. This antenna is a great dx antenna for anyone with a small lot or perhaps for an RV. Of course living 500 ft. from the Atlantic didn't hurt I suppose but have worked other hams using the Eagle located in such locations as the desert southwest and they had great signals as well. Follow the directions and you'll be working dx in no time. The antenna police made me take down my antenna but soon I hope to have the Eagle up and running again at another QTH. Thanks to GAP for making a fine product.

great antenna  Time owned: more than 12 months
We've had this antenna a couple of years, installed it on the side of the house, very poor results, lots of RF in the shack and high SWR.
Last spring we moved it and attached it to the barn about 100 ft away from the house and added four 30ft ground radials as well. Difference is night and day, antenna works great with decent SWR on all bands it's supposed to.
Instructions are crappy but with patience it is doable.

Junk  Time owned: 0 to 3 months
horrible instructions. something that would normally take me a few hours took me a few days. after assembly i tested it on the ground and it was perfect. put it on the roof and 40 and 10 meters went to 10:1 vswr. Where did my perfect go. grounded or not still the same. The only pleasure i got from this was sending it back. bought a hy-gain AV-640. that was very easy to assemble and works fine. As they say in England, mind the GAP

Good and Durable  Time owned: more than 12 months
I have had a GAP Eagle installed at this location since 1993.

Mine is painted green, and ground mounted near trees for a minimal visual impact.

The antenna performs equal to a dipole at 30 feet in height on 20m-10m and is super tough and durable. I cannot keep any wire up for one year, the wind always blows them down, the GAP just works for years and years without a care or worry.

The RF exits the antenna at a height where it has a chance to escape large ground loss as compared to a true vertical and there are no traps so 100 watts less your coaxial loss is what goes out.

This antenna is 40m "compatible", but is too short to use as anything other than an emergency antenna on 40m, any longer wire will beat it.

There are two ways I see to make this antenna fail for SWR, a botched application of the PL259 - that happens more often than you would think, and if you dont wrap electrical tape around the top of the steel pipe which is driven into the ground, it is possible that the rigid ground rods assembly will short to the mast upon assembly. The antenna will not tune this way.

The antenna is a dipole mounted on one end, not a vertical, and thats why the GAP antenna does not have the aggravating problems common to smaller than physical half wave antennas. But neither side of the antenna can be grounded, the entire antenna must be insulated from the ground pipe.

This antenna design has a major benefit in that it collects the signal from more polarity angles than a dipole.

As a test, I mounted crossed dipoles at 20 feet, one vertical and one horizontal and then put them on an A/B switch. I see from equal to S9 differences and it always changes within moments from one antenna to the next being the better.

The GAP has the vertical part of the antenna, the tuning rods, and the horizontal counterpoise
all working to accept the signal from many angles.

The GAP can be adjusted to better than 2.0 to 1 SWR on 20m-10m but it takes time and lots of trial and error. There are these "stubs" at the bottom of the antenna, which must be adjusted band by band and yes a change will affect slightly other bands, this is in the manual. What they dont say is the rods assembly can also be rotated small amounts around the antenna center vertical mast and that can provide the ultimate
best solution.

It sounds problematic, but it is consistent and can be dialed in with time, trial and error.

Some other antennas I have used (the Butternut Butterfly comes to mind) are loaded with reactance and are feedline length+orientation sensitive, they will truly drive you nuts. The GAP has a wide sweet spot and it can be found fairly easily.
