Below are my custom designed PL259 ( UHF ) Connectors.

I decided to turn the PL259 into a professional connector rather than use a inferior
style that are out in the market. I wanted superior cable retention, resolderability, a body and centre Pin

that wont tarnish, a trimetal plating suitable to all environmentswith high conductivity, a heavy duty centre Pin
material and right angles so I dont need heaps of adaptors to get equipment close to the wall and connections to
switch boxes and other equipemt thatmake cabling neater and easier.
I also wanted the HEX NUT so i could tension the connector rather than using inferior methods of tightening on a
barrel with only a knurl.

It is obvious you get what you pay for in the market but when spending thousands on amplifiers, radios
antennas, I could not dream of using a 2 dollar connector.

So I ended up with :
Teflon inner
Tri metal plating
Gold Centre Pin
Hex nut for Tightening
Straights and Right Angles
Crimp and Clamp versions
Available for many different cables ( RG series, LMR, etc )

Connectors can be seen at www.rfparts.com.au/public_html/amatuerradio.htm
