mini 14 foot rotatable dipole across the street its tiny 7-foot turning radius fits on the smallest roof it s perfect for town houses apartments and condos the mfj-1775 is inconspicuous and low profile not much bigger than a tv antenna and can easily be turned by a lightweight tv rotator see ar-35 page 63 it s no wimp its directivity reduces qrm/noise and lets you focus your signal in the direction that you want so you can work some real dx you can operate 6 bands 40 20 15 10 6 and 2 meters and run full 1500 watts ssb/cw on all hf bands coax features automatic band switching and uses highly efficient end-loading with its entire length always radiating with 6 and 2 meters thrown-in you have ham radio s most versatile rotatable dipole each hf band uses a separate efficient end-loading coil wound on fiberglass forms with teflontm wire and capacitance hats at each end no lossy traps 6 and 2 meters are fulllength halfwave dipoles built-to-last incredibly strong solid rod fiberglass center insulator and 6063 t-6 aircraft strength aluminum tubing radiator assembles in an afternoon adjusting one band has little effect on other bands mfj-1775w $249.95 warc band version for 12 17 30 60 meters only mfj-16b01 $19.95 built-in so-239 connector super strong uv resistant custom injection molded hang hole for inverted vees wire tie points light-weight center insulator for dipole antennas center insulator mfj glazed ceramic insulator now you can operate the low bands on 80 40 and 20 meters with a true rotatable dipole that ll blend in with the sky take advantage of the excellent propagation of the low bands during the low sunspot cycle this rotatable dipole lets you focus your signal in the direction you want so you can work some real dx small low profile inconspicuous the entire antenna length is used on all three bands the mfj-1785 is constructed of 6063 t-6 aircraft strength aluminum tubing with a solid center fiberglass insulator and handles 1500 watts ssb/cw the 80 and 40 meter end-loading coils are wound on fiberglass forms with teflontm wire and resonated with capacitance hats to ensure an extremely low-loss structure balun included 33 feet
