CHA-250B
The Comet CHA-250B is a newly design broadband vertical requiring NO GROUND RADIALS.
This antenna is EXTREMELY easy to assemble, requires no tuning or adjustments and VSWR is under 1.6:1 continuously from 3.5MHz - 57MHz!
It is not a 1/4 wave vertical, but an end-fed long wire type antenna with a matching transformer in a vertical position.
 
Broadband:  TX  3.5 - 57MHz
RX  2.0 - 90MHz
VSWR:  1.6:1 or less
Max Power:  250W SSB
Impedance:  50 Ohm
Length:  23'5"
Weight:  7 lbs 1 oz
Connector:  SO-239
Mast Size Required: 1"-2" diameter
Max Wind Speed:  67MPH

 

If you have the space, budget and desire to erect a full size antenna system we suggest you do so... bigger is better...however...if you live in an antenna restricted area and must manage with antenna or space restrictions or you simply wish to operate incognito you will be forced to make significant antenna compromises.  The CHA-250B will make the most of these circumstances!

CHV-5X
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 to solve the problem the minimal space presented.
 
NEW!!!  **Available at most Ham Radio Dealers Now**
 
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 do not 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.
 
Max power:  40/20M 150W SSB   
    15/10/6M  220W SSB
Horizontal length:  13 ft approx
Weight:  5 lbs 14 oz approx
Impedance:  50 Ohm
Connector:  SO-239
Mounting mast req'd:  1"-2.5"
Typical 1.5:1 or less SWR bandwidth:
  40M:  22kHz
  20M:  36kHz
  15M:  54kHz
  10M:  140kHz
    6M:  1.8MHz

H-422
The H-422 is a broad-band, compact, rotatable dipole designed to offer excellent performance even when mounted at only 10-15ft above ground in a V shape.
 
Heavy duty hardware and 2.5kW balun are included.
During assembly the user chooses any of the three pre-drilled holes to tune the 20/15/10M SWR dips to the low - mid - or upper band ranges simultaneously.  40M TX bandwidth tunes independently of the other three bands.
 
Frequency Range:  7, 14, 21, 28MHz
VSWR:  1.5:1 or less after tuning
Impedance:  50 Ohm
Length:  "V" shape  24 ft 5 inches
                Horizontal    33 ft 10 inches
Weight:  11 lbs 14 ozs
Max Power:  1000W SSB / 500W FM
Max Wind Survival:  67MPH
Wind Load:  3.01 sq feet
Connector:  SO-239
Construction:  Aluminum tubing, stainless steel hardware
2.5kW Balun included

HVU-8
Compact 8-band vertical base station antenna, 80/40/20/15/10/6/2M/70cm
 
8 bands and only about 8 feet tall!
 
Each HF band + 6M has it's own tuning stub.  Adjust the SWR to the desired band segment, then use an antenna tuner to TX outside of the 2:1 or less band-width.  2M and 70cm bands are pre-set at the factory and there are no adjustments.
 
The ground radial system is unique...the radials are screwed into 2 collars.  The collars can be rotated and fixed so all the radials are located to one side of the antenna....allowing it to be side-mounted on a tower, or next to a building wall for stealth operation.

Gain & Wave: 
80-6M:  1/4 wave
146MHz:  1/2 wave  2.15dBi
446MHz:  5/8 wave x 2  5.5dBi
VSWR:  1.5:1 or less
Max Power: 
HF:  200W SSB
6M -70cm 150W FM
Length: 8 6" (approx)
Diameter:  8' (max. approx)
Weight: 5 lbs 7 ozs
Connector: SO-259
