Description / Comet CHA-250HD 3.5-57MHz Base Vertical Antenna
Comet CHA-250HD HF/VHF Vertical Antennas is an updated design of the popular CHA-250B vertical antennas. This antenns makes the most of a tight situation! When you have too little space or too much regulation, theis antenna can offer easy assembly and setup, no ground radials, no tuning or adjustments. making this antenna perfect for an SWL wanting a low-profile, all-in-one antenna.
It features a new solid whip replacing the top aluminum section for greater flexibility and less strain on the lower sections in high winds. The “magic” behind the CHA-250HD is the transformer matching section. This improved design features a heat sink to dissipate the heat created inside the transformer from the RF that enters the power feeding section rather than transmitted as RF. This is the compromise needed to create a broad-band, low SWR, multi-band HF antenna with minimal visual impact.
When you are forced to play within the antenna and space restrictions of your QTH, Comet CHA-250HD HF/VHF Vertical Antennas can provide a clear winning advantage to getting out and making QSOs!
