Steve,

Somewhere, in the deep, dark recesses of an old NCJ magazine
there is an article by K2TNO, Bill Schrader, in which he describes
the results of a demonstration he did using multiple double female,
double male, straight and right angle connectors, connected in 
series, fed with a signal generator, swr meters, and a dummy load. 
The bottom line was that, even with more than a dozen of these 
connectors in line, the swr and loss was minimal, even at UHF 
frequencies. 

I looked for the text file I wrote up and sent to someone on the 
tower reflector, but could not find it (has anyone done a Find for
*.txt files on their computer recently??  It's housekeeping time!!).

Neither did I find the article title on the NCJ Cumulative Index
(curious....).

Maybe whoever I sent the text file to on the reflector will remember
it and put it up for you and all to read. 

73,
