FAQ:
Q: What is the VSWR of the comet cha-250b?
A: The Comet CHA-250B is a newly designed 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!
Q: Is the comet cha-250b a ground radial antenna?
A: The Comet CHA-250B is a newly design broadband vertical with NO GROUND RADIALS. This antenna is EXTREMELY easy to assemble, requires no tuning or adjustments and VSWR is under 1.6:1 from 3.5 MHz – 57 MHz!
Q: Which is the comet HF / VHF vertical antenna?
A: Comet CHA250B HF/VHF vertical antennas make the most of a tight situation! When you have too little space and too much regulation, Comet CHA250B HF/VHF vertical antennas can offer easy assembly and setup, no ground radials, no tuning or adjustments, and VSWR under 1.6:1 from 3.5 MHz to 57 MHz!
Q: How tall does a comet antenna need to be?
A: 1) Proper Height: The manufacture recommends installing this antenna at about 35 feet high with a grounded mast. For most of us concerned about appearances this is not practical. Below 15 feet this antenna loses power to the ground. I first mounted this antenna at about 9 feet off the ground and just took it down.
