With the popularity of Parks On The Air (POTA) and Summits On The Air (SOTA), more operators are optimizing their gear for rapid field deployment. Converting to BNC significantly reduces the size and weight of your kit while eliminating time-consuming threading, allowing you to instantly attach your coax with a secure quarter-turn twist lock.
Ditch the UHF to BNC adapter and convert your radio directly to BNC.
While two-hole chassis mount BNC connectors are available, their flange dimensions and hole spacing do not match the factory two-hole UHF layout. To bridge this gap, we offer a heavy-duty, 2mm-thick PCB featuring full front and back copper pours and plated through-holes. This provides a robust RF ground plane and a secure attachment point for high-quality panel-mount BNC options, such as the included Amphenol 112424 bulkhead connector.
This kit includes:
- One FT891 Conversion PCB
- One Amphenol 112424 BNC Connector
- One BNC Cap
- One Cap tether
Required tools:
- Soldering Iron
- Solder
- #1 Philips screw driver
- #2 Philips screw driver
Compatibility:
