Product Description

Thousands of Challengers are now in use throughout the world. From the jungle of New Guinea to the bitter cold of Finland to the brutal sands of Desert Storm, Challenger with its elevated feed links its user with the rest of the world. Challenger is the first and only antenna capable of operating on eight separate bands from 3.5 MHz to 144 MHz. Its operating bands are 80m, 40m, 20m, 15m, 12m, 10m, 6m, and 2m. Over 130 KHz of bandwidth is provided on 80m.

CQ tested the Challenger and on 40m compared to a mono band vertical, they found Challenger an S unit stronger. This is typical of the many reports received from amateurs around the world. Challenger is designed to be mounted directly in the ground or elevated. A ground mount is provided with each antenna. With the ground mount in place, the Challenger simply drops in. If necessary, because of space limitations, but not to improve performance, Challenger may be roof mounted since it does not require earth loss to obtain a 50 ohm match. Challenger requires a counterpoise of three 25ft. insulated wires. They may be buried or just scattered on the ground. Symmetrical deployment is not critical. Adding additional wire will not significantly improve performance. All of these are covered in a 16-page assembly manual provided with each antenna.

    Had my Challenger for 4 years now and it is great performer and great design – has withstood some tough winds. Moving North to another state and am, for sure, carefully disassembling and putting it up in the new home and property …. everybody oughta have one of these if limited on space and need great performance!

    Purchased my GAP Challenger DX 2 weeks ago and assembly was straightforward as the instructions were simple to follow. Nothing to change on the antenna as it performs exactly as per the specs on HF.
    The 20m performance is remarkable First three contacts were 2 VKs and Texas all within the first hour and then the following morning on 40m more VKs, US, Puerto Rico and UAE. Best of the lot was busting through the pile up on 15m for V55DX yesterday.
    It also had a bit of a battering on the second day with winds gusting 65mph, so pleased I guyed it for my own peace of mind!
    Cheers guys!

    Have had the Challenger up now for 3 months. I have it ground mounted here in Florid. It replaced a 5 band trap vertical. So far I have been able to break the Mid West and East Coast 20 and 40 meter mono banders and there
    Kilo Watt stations on all the resent DX expeditions with 2 or 3 calls and 200 watts. 20 and 40 meters the antenna really performs. 10 and 15 are OK, 80 meters it really needs some help. Haven’t tried the other bands. Can’t wait to get a amplifier for it. Ron KN4D

    Bought this antenna in 1993 in south Florida. I have a limited sized lot and the Challenger DX was a perfect fit. Well within my limited budget. While in S. Fla, it survived Tropical Storm Gordon along with many windstorms. Moved to Oklahoma in 1999. It was at two different locations in Central Oklahoma. It was taken out by a strong straight wind in 2010. The center insulator broke completely along with bending some of the vertical radiators. I repaired it and it’s still going strong. I moved to Wisconsin in 2014. It’s been on the air at two different locations here and works well. I use this antenna for digital only (JT9, FT8, PSK, etc). It’s a quiet receive antenna but it doesn’t compare to my 4 el yagi up at 60 ft. But it’s a solid antenna and if I were buying another vertical I’d buy another Challenger DX.
