The Hi-Q-4/160 Click to Enlarge
Remotely or Manually Tunable (your choice)
6 thru 160 meters

This is the LATEST innovation in HF mobile antennas! Comes in either the MT (Manually Tunable) or RT (Remotely Tunable - motorized) version

The Hi-Q-4/160 will cover the 10-160 M bands (i.e.: 1.8 MHz to 30 MHz.) It is the PATENTED version of the standard Hi-Q Series of HF mobile antennas. Similar in size as the Hi-Q-4/80, that is: 5" diameter loading coil by 10 " long (8" usable coil).

Mechanical details:

Base Length: 2' x 1.5" Stainless steel.
Coil Size: 5" x 10 " Polycarbonte (Lexan) tubing,
8" of coil is usable/tunable
Whip requirement: 160m: use 102' whip (not supplied) and
a CapHat with 32" lobes (supplied in Package B).
Will resonate at 1820 Kc.
80-40-20-17m: same as 160m
6-10-12m: use short 36" whip or CapHat only
Weight: Less than 8 lbs
Tuning Method : MT: Knob at the base, sliding up/down.
RT:
  • 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 use a simple DPDT switch to tune the antenna.

100 w I (rf): 2.1 amps

Performance:

1.8 Mhz
Radiation Efficiency: 1.3% **
Relative radiated power: -19.2 dB
Feed point impedance: 22 ohms
Bandwidth for 2:1 VSWR 19 kHz
3.750 Mhz
Radiation Efficiency: 12%
Relative radiated power: -9.2 dB
Bandwidth for 2:1 VSWR 35 kHz
Coil "Q" 450
7.2 Mhz
Radiation Efficiency: 43%
Relative radiated power: -3.7 dB
Bandwidth for 2:1 VSWR 120 kHz
14.2 Mhz
Radiation Efficiency: 77%
Relative radiated power: -1.1 dB
Bandwidth for 2:1 VSWR 475 kHz

Excellent performance on the rest of the higher bands!

** NOTE: If this was a BRAND "X" screwdriver antenna it would have a Radiation efficiency of Less than 1/10th watt (that is right, one tenth of a watt out of your 100 w. radio)... a real QRP set up. And, yes, QRP rigs get out, but with the Hi-Q Series antennas you WORK THE WORLD!

Plug-n-Play Packages Available! (RT Remote Tune Model Only)

Package A


Package B Supply your own coax, two or four conductor cable and connector (power / turn-counting), ~4ft whip, controller or DPDT switch and antenna mount, and you are on the air!
