The Hi-Q-4/80 RT

Remotely Tunable (Motorized) - 6 thru 80 meters

The Hi-Q-4/80 RT is a motorized, Remotely Tunable HF Mobile antenna. This is the MOST efficient motorized tunable HF Mobile antenna built today. The coil diameter is perfectly chosen and optimized at the 40M band with only small performance change on 80 and the higher bands.

Dimensions:

Antenna height: 3 feet

Recommended whip length: 7 feet 6 inches

Loading coil diameter: 4 inches

Loading coil length: 9 inches

Mast diameter: 1.3 inches with 2 inch motor housing

Weight: 7.0 lb.

Base impedance: 18 Ohms @ 3.8 MHz

Matching may be needed for 40 & 80 meters, using either a shunt coil or other matching device. The loading coil is a sealed unit, no maintenance is required.

Method of tuning:

MFJ-1922B or similar controller. ALL Hi-Q-Antennas now have a magnet to count rotations of the motor-output shaft. So, by adding an optional reed switch externally, you get a "pulse per revolution" for the MFJ-1922B or similar controller.
You may also use a simple DPDT switch to tune the antenna.

Power input to motor: 12/24 VDC
Mounting: 3/8-24 bolt, two insulating wafers, supplied. Mid support is recommended.

Electrical parameters (Measured @ 3.8 MHz)

Frequency coverage: 6 meters through 80 meters (for 6m & 10m use a short whip)

Overall height: 13'6" mounted on a Std. Vehicle

Overall antenna "Q": 93

Radiation Efficiency: 7.2%

Relative radiated power: -11.4 dB

Power handling: SSB legal limit
