Hi-Q Piranha 5R/80

The NEWLY developed PIRANHA series of Hi-Q Antennas are the derivative of the Military On the Move HF mobile and fixed station antennas.

Major improvements:

  • Hi-Impact Modified Polycarbonate coil housing
  • Silver Plated # 12 propriety coil wire
  • NEW disc with Silver Plated BRASS balls for precision tuning.
  • Lower mast is 2’ long, black anodized, OR 1.5 inch Stainless Steel.
  • Silver Plated WQD is installed at no extra cost.
  • Mounting hardware Included.

Remotely Tunable 10 thru 80 meters

This is the LATEST innovation in HF mobile antennas! It is the PATENTED version of the standard Hi-Q Series of HF mobile and base antennas. The loading coil has 9.5″ usable travel with approximately 350 uH inductance.

Lower mast, below coil:2′ x 1.5″
Coil Size:5″ diameter x 11.5″ long, Lexan
Whip needed:80m: 102″ whip (not supplied). No CapHat needed, however it will improve Radiation Efficiency if used.
80-10m: 36″ to 60″ whip (not supplied)
Photo Shown is: Hi-Q-5/80 RT with 2′ Extension Rod and 32″ CapHat.
Weight:8 lbs
Tuning and Controller Information:MT: Knob at the base, sliding up/down.
RT: The RT version has a Precision 12VDC Gearhead Motor (NOT a screwdriver!)Recommended Controllers:

  • 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.
  • Simple DPDT switch.

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!
