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, …
Dual-band 2M/70cm HT Antenna Super flexible and lightweight, about 1/8″ diameter, made from similar material as unbreakable eyeglass frames. If your desire is to increase the range and signal strength of your HT, this is the standard upgrade antenna for any HT with a BNC connector. Gain & Wavelength: 2M: 2.15dBi 1/4 wave 70cm: 3.5dBi …
DualBand 2M/440MHz mobile antenna Very short yet efficient antenna, mainly used in metropolitan areas where extended range is not critical. Particularly used in a city or area where the repeater sites are generally higher than the mobile station due to the pattern having an uptilt. Gain & Wave: 2M: 1/4 wave 70cm: 2.15dBi …

The CST-30 is an adjustable antenna mounting 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.
Window/door feed-through coax cable jumper The CTC-50M jumper allows you to get your antenna coax into the radio room without drilling holes in the wall or leaving a window/door open. The center core of the flat wire coax is “copper-clad steel”. It was chosen for its strength and resistance to metal fatigue. The film is …
