MFJ-2010

OCFD UltraLite Dipole

Ultra-Lite™ for 40, 20, 10 and 6 Metres, handles 300 Watts PEP SSB/CW. Perfect for low-profile, portable and QRPoperation.

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, solid gain, and full-frequency agility without a tuner!

Key Features

How good are they? W4ILV bought an MFJ-2012 and wrote EHAM, “. . . the best wire antenna I’ve ever used!” We think you’ll agree, and here’s why:

Highest Efficiency:
Full-sized radiator with MatchmakerTM feed block that tests over 98-percent efficient. All your power gets radiated!
Best Match:
NEC-modeled element delivers the same feed-point impedance on every band. Innovative new transformer designs yield 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 feedpoints are compensated for typical mounting height, so you always get lowest possible SWR on all bands!
Frequency Compensation:
Normally, a OCFD cut for 3.85 MHz resonates on 7.7 MHz. Ourunique OCFD design resonates mid-band on both 75/40!
Built to Last:
UV-resistant marine-ABS feedblocks, stainless hardware, and Teflon® SO-238 connector ensure maximum protection from the environment.
Easy-to-Install:
Installs in flat-top or inverted-Vset-up, feedblock has attachment points for tower or tree support. Suggested height is 35-70 feet.
Low Cost:
Outperforms multi-band vertical antennas by a wide margin for an unbelievable fraction of the cost!
