Comet CHL-25S Dual Band Mobile Antenna 2m & 70cm, 144/430 MHz, 200W, Foldable

The Comet CHL-25S is a high-performance dual-band mobile antenna for 144 MHz (2m) and 430 MHz (70cm), featuring a foldable element for practical vehicle use — ideal where a rigid full-length antenna would be impractical in car parks or low-clearance areas. Rated at 200W on both bands with genuine gain figures of 2.15 dBi on 2m and 5.5 dBi on 70cm.

The wide-band receive capability (100–170 MHz and 350–470 MHz) extends reception beyond the amateur bands, making it useful for monitoring public services, airband, and other VHF/UHF traffic alongside normal amateur radio operation.
