Anyway you look at the Hi-Q-HF Mobile antenna series: IT IS the best performing SHORT remotelly  Tunable antenna out there! 

The NEW IMPROVED Hi-Q-Antennas™ Series HF Mobile antennas are the latest, 6th generation design by Charlie Gyenes W6HIQ / VE7BOC / VA7HIQ / HA5CMG. These Hi-Q-Antennas™ products are covered by one or more of the following patents: US 6,275.195 B1, US 6,496.154 B2.  

Design philosophy: Center loaded, remotely tunable in the HF band, using high-quality German Planetary Gear head, 12/24 VDC motors. (Not a cheap screwdriver types like brand X makers -- for a more in-depth comparison between the Hi-Q-Antennas design and screwdriver-type designs,
 click here.).
 
The recently released for HAM use the Hi-Q-6/80 RT MC-3-H and the Hi-Q-6/160 RT MC-3-H Ruggedized antennas where developed for the USMC On the MOVE vehicular installations.

Those antennas are now serving our militaries HF communication needs. 

No moving parts outside, No length changes. The contactor (RF coupler) travels within the sealed coil
housing, kept out of the harsh environment. Silver plated Beryllium copper finger stock is in contact with two
turns of the coil, 720 degrees, at all times. The RF De-Coupler contacts the silver or copper plated tubing that
is activated by a stainless steel all-thread to provide the linear actuations.|

Why this antenna is BETTER than ANY other so-called screwdriver types? Hi-Q-Antennas™ RADIATE not DISSIPATE! For a more in-depth comparison between the Hi-Q-Antennas design and screwdriver-type designs, click here.

Compare our Radiation Efficiency to the competition. Ask the competition if they even have any data! We measure our HF Mobile antenna performance with Hewlett-Packard test equipment to back up what we advertise! Remember, one TEST is worth a thousand so-called expert OPINIONS.

Note:  To be able to efficiently utilize the 6 meter band on any Hi-Q Antenna, one MUST utilize an antenna analyzer, find the 5/8, 3/4 or even the MULTIPLE wavelength resonant point. This is due to the fact that the total antenna height exceeds 1/4 wavelength. Some hams have found it advantageous to dedicate a small 6-meter antenna, in addition to their Hi-Q Antenna. If you have any questions, please let me know.

Every criteria pertaining to a center-loaded antenna (23 of them) is seriously considered and applied. Most importantly:

What counts in a CENTER LOADED HF mobile antenna is the LOADING COIL and it’s parameters.

That is why the Hi-Q-5/3-30 MC-3 HF On the Move antenna is in COMBAT service in Iraq!

Ask the brand-X makers to publish their coil “Q”! 

  • Coil diameter and wire spacing for high "Q"
  • Coil wire diameter for low resistance and minimum # of turns
  • Coil housing: Lexan, (Polycarbonate) tough UV protected
  • Coil wire embedded into the Lexan housing for shape and rigidity
  • Coil Cap and Base is precision CNC machined from 6061-T6 aluminum and nickel plated for conductivity. GOLD and STAINLESS STEEL are available as options -- contact me for pricing.
  • The entire coil housing is SEALED with neoprene "O" ring.
  • No moving parts outside, no height changes while tuned.
  • Computer modeled for optimum Radiation Efficiency
  • Base length below coil is: 3' for optimum "center loading"
  • Maximum whip length recommended (to reach 13'6") for best performance
  • 6061-T6 aircraft quality aluminum used for base tubing's
  • Silver plated brass tubing for the RF De-Coupler
  • Silver or gold plated Beryllium copper finger stock for conductivity and flexibility
  • All materials used are Mil-Spec, precision machined and hand fitted individually.
  • All stainless steel hardware.
  • Stainless steel lower mast, or black anodized on the MC-3-H antennas
  • Mounts with a single 3/8-24 Stainless Steel bolt or ½-20 bolt on the MC-3-H.
  • Matched to 52 ohms with an MFJ-909 antenna matcher.


Compare before you buy!  
 
See if ANY other tunable antenna comes close.

We have designed and delivered submarine antennas to the US NAVY and other foreign vessels.

Special HF antennas for the US ARMY, Marines, Air Force and Homeland Security. In addition, many foreign military. 

Who DOES the brand –X makes selling to?

That is right ONLY to you: HAMS and HAMS are more critical then some of the government buyers, YOU know better!

Why would you spend good money a screwdriver CONTRAPTION when you can get a REAL HF antenna from Hi-Q, SPECIFICALLY developed for you demanding needs?

NOW FOR LESS MONEY!

Yes, when you compare QUALITY and PERFORMANCE it is WORTH more, therefore it COST LESS! 

So it is time to TRASH those screwdriver types and UPGRADE to a REAL HF Hi-Q Mobile antenna.
