  1. Exactly What I Needed 5 Star Review

    Posted by on 11th Aug 2017

    These connectors are exactly what I needed. They are top quality.

  2. Just what I needed, 5 Star Review

    Posted by on 16th Apr 2017

    Making a window interface that was 1-1/4 thick, the 1-3/4" bulkhead connectors I had would not work. The 3" I ordered from American Radio Supply were just the right size with plenty of thread on both side to connect my coax and water seal the outside connection. Great service

  3. These work GREAT! 5 Star Review

    Posted by on 12th Feb 2016

    I ordered five of these, to make a window frame pass-through for HAM radios and a scanner. They work perfectly, and do not come apart every time I disconnect the coax (unlike another three-letter branded item does.) They are a little more expensive, but worth it. I wholeheartedly recommend... AmericanRadioSupply.com.

  4. Fit the ticket very well... 5 Star Review

    Posted by on 19th Oct 2015

    I needed bulkhead connectors for a DIY project to get my antenna cable coils out from under my 'shack desk'. To make this increasing clutter more manageable I decided to coil them outside the window to my shack and build an intermediate connection point to be mounted at the bottom of the window sill, these fit the ticket very well, providing a tight, weather proof fit into a well trimmed 2x4 board keeping the primary cables outside and allowing short extension cables to the ever growing herd of amateur radio inside.
