CB-28P Made by Hamg Shing in Taiwan 10 years ago, sold thousands to dealers and distributors. Here is a final inventory clean up of a discontinued item. Hamg Shing is a high grade Taiwan maker now based in China. They supply only car factories now.
This antenna mounts on a vertical narrow surface like the windshield pillar of many cars and trucks. It is 24" retracted and 60" fully extended length. The telescopic mast assembly screws into the special side mount chromed base then secures with small set screws. Allen wrench included. The mast is all stainless tubing then top section is gray plastic encased coil. The tip has a thumb head adjustment rod for fine tuning of the frequency. The cable is 79" long with a male Motorola connector.
This connector was meant to plug into an am/fm coupling box which permitted the antenna to work for the am/fm radio as well as the CB. But the adapter box is not included, already sold out. (Cut off this connector and add a UHF male for direct connection to a CB or buy it in our store and we attach it for you) The adapter box C-27 does come with our CB-27S other listing in our store. Power handling is guaranteed for 5 Watts legal CB power. Never tested high power on it but we estimate it should be good for 50 Watts and maybe 100. Outside the USA and the FCC of course.
Antenna installes with the just one upper and one lower sheet metal screw plus requires the hole for cable entry. Hard to find item, this is the last of them here.
