Remotely Tunable 6 thru 160 meters

Note: This NEW Hi-Q-4/80 and -4/160 Rt MC-1 antenna has the specially developed Hi-Impact/Modified Polycarbonate coil housing with Internal components SILVER-plated.

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: 4" diameter loading coil by 10 " long (8" usable coil).

Mechanical details:

Base Length:	2' x 1.5"
Coil Size:	4" 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:	6 lb
Tuning Method :	MT: Knob at the base, sliding up/down. RT: All Hi-Q antennas now have REED SW and dual MAGNET installed to provide TWO pulses per revolution, utilized by the Hi-Q DC Controller. You may use a simple DPDT switch to tune the antenna.

Relative radiated power:	-19.2 dB
Feed point impedance:	22 ohms
Bandwidth for 2:1 VSWR	19 kHz

3.750 Mhz

Radiation Efficiency:	8%
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!
