[TowerTalk] PL259 Insertion Loss?

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?
