Hi-Q Piranha -5/160 R-MIL
Military Spec Version of the -5

 

PIRANHA Antenna Specifications.

 

Description:

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.
                Silver Plated WQD is installed at no extra cost.
                Mounting hrdw. Included.



Remotely Tunable 10 thru 160 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.

The Hi-Q-5/160 will cover the 10-160 M bands 

Mechanical details:

Lower mast, below coil:: 2' x 1.5"
Coil Size: 5" diameter x 11.5" long, Lexan
Whip needed:

160m: 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-5/160 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.

 

Electrical details: (mid-mounted on standard auto)

Freq: 1.8 MHz
Base length: 2'
Base diameter: 1.5" 
CapHat: 32 inch lobes
Radiation resistance: .2 ohms
Electrical length: 8 degrees
Degree-amp: 4.8
Estimated ground loss: 6 ohms
Overall antenna: "Q" 83
Top, whip: 102"
Shunt: 2300 pF for L match to 52 ohms
Power handling: SSB legal limit

Coil data:

Inductance: 350 uH
Reactance: 3140 ohms
Wire size: 12 AWG
Coil diameter: 5"
Coil length: 10" (8" usable)
Pitch: 11
Coil "Q" 580
Loss resistance: 16 ohms
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! 

The Hi-Q-5/160 antenna is similar in construction to our Military version, with the exception that the CAP/BASE of the coils is 6061-T6 aluminum.
