MFJ-1662
HF-6m Mobile Screwdriver Antenna
Don't forget to look for the appropriate automatic screwdriver antenna tuner from TurboTuner! Proudly made in the USA, the TurboTuner comes in three models: ITT-1 for Icoms. KTT-1 for Kenwoods, and ZTE-YTT-1 for Yaesu.
The MFJ-1662 (40-2 Meters) is termed a Mobile Antenna because it covers its respective frequency ranges with the short 4½ foot (23 inches collapsed) mobile telescoping stainless steel whip. A 10 foot telescoping whip (19 inches collapsed) is included for fixed mobile operation only. It vastly increases efficiency when you are stopped at a hotel or rest stop, etc.
The MFJ-1662 Mobile Screwdriver Antenna covers 40-2 Meters with 4½ foot mobile or 10 foot fixed operation telescoping whip. Continuously adjustable loading coil is 15 inches long by 2 inches in diameter and weighs 1.3 pounds.
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.
