 I can understand that. UHF connectors despite their name are Lousy at
higher frequencies.                                  
 The 75 Ohm "TV" type cponnector as you saw would be better. You will
still be loosing some power(reflected back to the transmitter) becasue
of the Impedence Mismatch but as you have proved not as much as using
the PL fitting.
 The mismatch damage is a prolbem with higher powered transmitters. I
highly doubt a 802.11 transmitter would be hurt.
