Along time ago a fellow did an article for NCJ magazine.  he  hooked up 
around 25 or 30 various elbows, barrel connectors etc and did a loss  test.  He 
came up with the whole string being no more than half a dB if I  remember 
correctly.  Of course if you are using Chinese connectors of  dubious quality 
who knows.

I've always assumed that UHF connectors had negligible  insertion loss 
below 30MHz, but I recently spotted a couple of quotes on  the web that 
put losses between 0.3 and 0.5db @ 30Mhz. If that were the  case, the 
cumulative effect of a typical installation with 6 to 8  connectors would 
not be so negligible, especially on 10 and 12  meters.

I was wondering if anyone has done any tests of their own or if  they 
know of a reliable source on the web for this kind of data? Another  
thing that comes to mind is whether there is any additional losses  
associated with UHF crimp-on connectors?
