Dave, If you have all these adapters in line feel lucky with only 1 db loss.
Good adapters are sometimes hard to find unless one wants to spend some real money. The Radio Shack and most at hamfest are junk...works good on CB I guess. I've seen barrel connectors with 3 db loss at 150 MHz. ron --- In [email protected], "Dave VanHorn" <[EMAIL PROTECTED]> wrote: > > > This one is a bit funny.. > > As part of the big project this weekend, I had this UHF amp with > output on a pigtail with a BNC male on the end.
