It's all fun at UHF!
connectors are available in every fitting and when properly terminated present the lowest loss.
10m LMR400 = 1.1dB ~ 19% loss
10m LMR600 = 0.7dB ~ 12% loss
That's why this type of coax
is expensive. The trick at UHF is to keep coax
runs as short as possible.
Pay extra and you can have coax
cable cut to length and terminated professionally.
Properly terminated UHF pigtail adapters, (can usually be purchased ready manufactured in virtually every fitting), present such a small loss that it's not worth worrying about.
None of this an issue with commercial installation but hits the wallet for hobby use.
Just my tuppence worth.
All the best,
