These are high performance components that add up to a high performance antenna set up.
The connectors are high grade solder on connectors. Solder on connectors are far superior to commercial bought crimp on connectors.
The coax is a top grade RG8X coax which is a low loss coax that ensures that the whole radio wave is transmitted out the antenna. RG58 coax is used a lot by people who don't know much about coax. I have used it forty years ago when I didn't know any better. It looks the same as RG8X and is cheaper but in radio you really get what you pay for.
RG58 is a high loss coax and not worth installing if you expect high performance since a lot of your signal is lost before it ever hits the antenna.
I pre-tune each antenna so the customer can rest easy knowing he or she has a high performance system.
I also include an attached ground cable and include instructions in how to set it all up
Each system comes with a custom made antenna mount
