Eagle Antennas. Made by us in Wales for discerning radio amateurs
We build them strong and we build them well. Our pricing is sensible and reflects the cost of materials and assembly time. We provide the best value you can get.
We are particularly keen on the absence of bullshit about our antennas, and pages of nonsense techno-babble which seeks to justify absurdly high prices. Check the gain numbers of the "wonder" antennas with our antennas. Then compare the prices and build quality.
When you buy an Eagle antenna it has insulated elements only where it is necessary, as in the duoband designs where interactions can arise. When we use insulators we don't use them to support an element significantly above the boom as this is a weak point particularly if the insulators are fixed to the boom by just one or two screws at the centre of the boom. At the centre of a well-designed antenna the current will be zero at resonance. Therefore - no need to insulate it, except at the driven element if the matching system requires that, or with our duoband 6 and 4m antennas where interactions are certainly an issue.

All the above elements use strong 3" x 3" X 1/8"aluminium plates which have the advantage of 75mm spread between the insulators or fixing screw locations. This gives the greatest mechanical stability. Again, when the plate is attached to the boom, the 75mm screw spacings gives great strength. Insulators are UV-resistant nylon for long life even in sunnier climates.
2m antennas are built with either 1" or 1-1/4" square booms depending on model. 5mm solid rod on top-hat insulators is used for the elements, a proven and mechanically stable design. Matching of the 2m antennas is via adjustable driven-element and T-match, thereby allowing both impedance and resonance to be adjusted. This is particularly useful if other antennas are nearby, with detuning effects.
At Eagle we dont claim that only our designs work and that we are the only people who can produce a good VHF antenna. We use professional software to design our antennas, both mechanically and structurally. Using the average of 3 modelling programs we then build and prototype our antennas carefully.
At Eagle we make our 6M and 4M antennas with 5/8" tubing at the centre to reinforce the 1/2" tubing used for the remainder of the element. We do not use cheap and weak 3/8" hollow tube material for the element tips. The 2m antennas use the proven "through the boom" element arrangement, with known correction factors for boom and element size.
At Eagle we have been making antennas for over ten years. We know that most hams want an antenna that will go up and stay up, and many of our original ten year old models are still working well. That's because we build them very ruggedly. We research weak points such as insulators and minimise their use. Our insulated elements are raised only 5mm above the boom and are 1-1/2" either side of the boom, giving a bearing surface of 3" overall. This gives the most mechanically stable arrangement possible.
Some of the antennas put on the market recently make exaggerated claims about performance and construction and bombard the ham with a ton of bullshit. We simply refuse to do that. Instead we focus on the quality and performance of our product. Do the comparisons. We offer better value by far.
At Eagle we use A2 stainless steel (not "Marine grade" which means nothing) for all fittings except for mast U-bolts which are heavy zinc-galvanised.
Out of the many compliments we have received on our antennas, we reproduce just a few below.
I'm impressed that it is still in good condition after this time. (M1CNK on his 8-year old 6M3dx antenna)”
It was straight foreword to assemble, spot on in tune (once I remembered to attach the balun to the DE). - Martyn - G0THY (4N6 duobander)
Just dropping you a line and a second thank you for the 6m Moxon that you supplied along with all the bits & Pieces I needed to go portable with. It takes around 5 Minutes to set up from scratch & the moxon fits in the car without having to dismantle it. The 6m Moxon is a sure winner. First time I tried it I got to the states several times and I am currently scoring highly in the 50Mhz UKAC championships (actually Top in 50m UKAC this month in the restricted section) The service is always excellent and I would not think about shopping anywhere else. Kindest regards David M0NUT
I am very happy with the Amp.& the Eagle 6elem.6mtr. antenne I bought last year.
Ron thank you very much for your help - Finn Rasmussen OZ8FR
The beam (Eagle 4M4DX) arrived this morning. Very impressively engineered. The proverbial battleship comes to mind! I just put my analyser on it it it's spot on. I hope to get it up in the air over the weekend. - Dave G4OER
Dipole up and running no problems (SWR 1.2 across band with tuner in), worked around Europe, best DX so far EA9. Thanks for all your help, really glad I got in touch with Vine (custom built 6m rotary dipole) - Richard M0RBG
Just FYI, managed to work JA on 6 this year using your prototype 6/4M (3+4) antenna, brilliant. 73 Tim M0AFJ
The antenna arrived here today by TNT. Had a look at it now and it is a nice piece of antenna :) Morten - LA9DFA - re Eagle 4M6dx
I hope everything ok on your side, here all ok, and enjoying the 70 Mhz, finally I caught some ES and also worked some other via meteor Scatter, so your 4M6dx antenna is doing excellent job for me. Biel EA6DD
Thanks very much for the 4m6DX which arrived very quickly. I found it very easy to assemble and fit to my mast. The F/B is impressive. I've worked six new countries in the last two weeks. Thanks very much. - Tony G3PFM
I never doubt on you and your antenna's. But you have still surprised me. The
6M5DX, which I bought from you few months ago, works
EXCELLENT, and I mean this, really and with the capital letters. Whatever I
heard, I worked, no linear so ever, just barefoot - 100W, and with superb
antenna. There was an opening couple of times, I have had 51 new DXCC counties
from since (44 in two days - 24/25.5.2010)6M5DX was in the air on 24.5.2010. I
just have tasted the flavour of the magic band, hi.Also, the SWR is FLAT (1:1,0) from the start of the band till 50,200; on 50,250
is SWR 1:1,1 and on 50,500 is still superb (1:1,3). I can go athe way up to
52,000 and plus, the SWR is below 1:3 (1:2,5). Antenna is approx. 40' high.
And all this with NO ATU. Furthermore, no TVI's and other crap, no neighbor's
problems, nothing, hi. Assembly of antenna is easy, peace of cake.
I am very pleased, and I will (actually, I am telling already) tell the guys on
the bands about it (many already know for it, as soon as I mentioned the Vinecom
and 6M5DX EAGLE). Dusan, S52DD
