MFJ-2289 Big Ears portable dipole 7–55 MHz
Portable V dipole tunable from 7.0 to 55 MHz, 1 kW PEP, built-in Guanella balun, aluminium and stainless steel
The MFJ-2289 Big Ears is a general-coverage portable V dipole: it tunes to a very low SWR on any frequency from 7.0 to 55 MHz and handles 1 kW PEP.
Product description
It has few parts to assemble and a quick tuning procedure. With 34 ft (about 10.4 m) of radiating element it does not suffer the losses of large loading coils.
The Guanella balun is built into the feed assembly, effective across the whole tuning range, for consistent performance and maximum RFI protection. The V shape keeps the element tips high, protecting you and those around you from accidental contact.
The rugged aluminium and stainless steel construction ensures years of reliable service.
