MFJ's new Manually Tuned Screwdriver Antennas let you operate all bands 80-6 Meters continuously including all WARC bands and the new 60 Meter bands (depends on model). It far outperforms other HF compact antennas.

An extra long 10 foot (19” collapsed) telescoping whip lets you really get out and work rare DX! A 4½ foot (23” collapsed) telescoping stainless steel whip is included for mobile and limited space operation.

It has a highly efficient loading inductor. For highest Q, the coil is wound with heavy gauge wire with wide spaced turns on a core that is mostly air.

A tuning sleeve electrically removes turns to eliminate detrimental self-resonance effects that "wander leads" cause. The tuning sleeve is on the low impedance side of the coil to minimize power robbing stray capacitance and detuning hand capacitance effects. Tuning is smooth, easy and sure -- the frequency stays put after you tune it. There is no tedious back and forth trial and error tuning procedure.

It's extremely rugged -- the whole coil assembly is one unit and does not move. A separate movable sleeve adjusts frequency. A nylon-tipped thumb-screw locks sleeve. A wing nut lets you connect a matching capacitor or inductor for 1:1 SWR.

Standard 3/8x24 mounting hardware is used for both the loading coil and both whips. Use any standard 3/8x24 mount.

Works great in or out doors. Handles 200Watts PEP. Add coax, connect ground/ counterpoise and you're ready to operate.

Portable Manual Screwdriver Antennas

The MFJ-1664 (80-6 Meters) is termed a Portable Antennas because it covers its respective frequency ranges with the long 10 foot (19 inches collapsed) telescoping whip for fixed operation. They are smaller and lighter than the mobile versions. A short 4½ foot (23 inches collapsed) telescoping whip is included for limited space or mobile operation.

The MFJ-1664 Portable Screwdriver Antenna covers 80-6 Meters with 10 foot whip. Covers 6-40 Meters 4½ foot whip. 24 inches long by 2 inches in diameter. Weighs just 1.8 pounds.
