I had used this product before with great success (five years plus). It is very easy to install with only pliers needed. And the radio transmission and reception is very good.
If you're a novice with soldering and you are working with a 30 foot tall boat mast.....I highly recommend it.
It's a little on the expencive side but it's easy to use
All you need is a pair of plyers and a knife . Works great .easy to use since it is gold plated there's no ohm loss I actually think it improved the receiving of my radio( not sure how but it seems to have)
