CHA-250HD (New version of the CHA-250B). The top section of aluminum has been replaced with a solid whip for greater flexibility and less strain on the lower sections in high winds. . The CHA-250HD Transformer Section This is a the “magic” behind the CHA-250HD, the transformer matching section. The transformer on the original CHA-250 had smooth sides. The current version has a heat sink to dissipate heat created inside the transformer. Yes, some of the RF that enters the power feeding section is turned into heat rather than transmitted as RF, but that is one of the compromises needed to create a broad-band, low SWR, multi-band HF antenna with minimal visual mpact. 3.5-57MHz. 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 3.5-57MHz!
