Manufacturer description
This onelinkmore 4-Type BNC to UHF Adapter Kit solves the connector-mismatch problem that stops most scanner and CB radio upgrades cold. The set includes all four gender combinations: BNC male to UHF female (SO-239), BNC female to UHF male (PL-259), and both reverse pairs, so you can adapt any cable to any radio without a second trip to the parts bin. The most common use is running a heavy-duty PL-259 antenna cable from a rooftop or mag-mount antenna into a BNC handheld scanner or HT, which pulls in far more range than a stock rubber duck antenna. Built from brass with nickel plating, these…

Frequently Asked Questions
Will this let me connect my base antenna to a handheld scanner?
Yes. The BNC male to UHF female (SO-239) piece accepts a PL-259 antenna cable from a rooftop or mag-mount antenna and plugs straight into a BNC handheld scanner or HT.
What is the difference between PL-259 and SO-239?
PL-259 is the male UHF plug and SO-239 is the female UHF jack. This kit covers both against BNC male and BNC female, which is why it ships as four pieces.
What frequency range do these adapters handle?
onelinkmore rates the set for 0-1000 MHz across 50-ohm RF applications, covering HF, VHF and UHF. Check the product listing for power-handling specs.
Are these compatible with a Uniden Bearcat scanner or an SDR dongle?
The listing names Uniden Bearcat scanners, Cobra handheld CB radios, ham HTs, SDR dongles and legacy BNC security cameras. Confirm your device uses a BNC jack before ordering.
What are the connectors made of, and is there a warranty?
Brass with nickel plating and precision-machined threads, plus a knurled grip for hand-tightening. A 12-month warranty is included; see the listing for current terms.
