Portable HF Antennas


This is the compact dipole used for HF communications on the set of the ABC Television show “Last Man Standing” with Tim Allen. The crowded space above the set required a compact multi-band dipole and the CHV-5X was selected as the best option.


5-Band, 1/2 wave rotatable dipole for 40/20/15/10/6 meters!


Compact, lightweight, and easily assembled in either a horizontal, “V” shape or ground-plane configuration. Each band tunes independently of the others.


Comet engineers have specifically designed this antenna for those that desire a milti-band dipole that can be rotated if needed, but don’t have a lot of room to install it.


If you have antenna restrictions, neighbors that tend to complain about antennas, simply want to operate without drawing attention…or you want a lightweight multi-band antenna to use in portable or emergency situations, the CHV-5X is a great choice.

The “HFJ-350M Toy Box” is the HFJ-350M antenna as described above….

+ the “L-1.8/1.9” 160M coil

+ a vinyl roll-up carry case

(160/80/40/30/20/17/15/12/10/6M bands)

Convenient roll-up kit with extra slots and pockets to store accessories like adapters and a counter-poise

Unroll the case and decide how you will “play radio” portable!

The CST-30 is an adjustable bracket designed to fit the IC-705, FT-817 and FT-818 radios.

A jumper is included to adapt from the BNC connector on the radio to an SO-239 connector for the HFJ-350M Toy Box or similar antenna to screw onto.
