Ultra-lite for 40, 20, 10 and 6 meters, handles 300 Watts PEP SSB / CW. Perfect for low-profile, portable and QRP operation.
Virtually invisible 66-foot jacketed wire element. Delivers up to 6-dBi gain on 40 meters, 9-dBi on 20 meters, and a whopping 11.5-dBi gain on 10 and 6 meters! Day or night, there’s always DX on one of these bands. If you hear it, you’ll work it — even on QRP!
Engineered from the ground up, innovative new antennas by K1BQT break traditional OCFD design barriers to deliver wider bandwidth, lower SWR, a solid gain, and full-frequency agility without a tuner!
Highest Efficiency: Full-sized radiator with matchmaker feed block that tests over 98-percent efficiency. All your power gets radiated!
Best Match: NEC-modeled element delivers the same feed-point impedance on every band. Innovative new transformer designs yield the exact ratio needed for a great match.
Super Balun: OCFDs need good baluns to block feedline radiation. Built-in bifilar-wound Guanella current-choke has over 30 dB of common-mode rejection on all bands. Kills pattern irregularities, RFI, noise.
Real Gain: Delivers a 6-dBi ground-rein-forced dipole pattern on the fundamental and a 9-dBi full-wave cloverleaf on the second harmonic. You get an amazing (up to) 11.5 dBi peak gain on higher bands.
Height Compensation: Element feed points are compensated for typical mounting height, so you always get the lowest possible SWR on all bands!
Frequency Compensation: Normally, an OCFD cut for 3.85 MHz resonates on 7.7 MHz. Our unique OCFD design resonates mid-band on both 75 / 40!
Built to Last: UV-resistant marine-ABS feed blocks, stainless hardware, and teflon SO-238 connector ensure maximum protection from the environment.
Easy-to-Install: Installs in flat-top or inverted-Visit-up, the feedback has attachment points for tower or tree support. The suggested height is 35 – 70 feet.
Low Cost: Outperforms multi-band vertical antennas by a wide margin for an unbelievable fraction of the cost!
