For whatever it's worth, my run of approximately 250 feet of 3/4" CATV
hardline measures (with an Autek RF-1) to have 1.6 dB of loss at 28 MHz -
not nearly so good as the Handbook table says it should be (about .36
dB/100 fit). Of course, this includes 2 home-brew UHF connectors. I've
checked for moisture infiltration, etc., but this is about what the
installation measured right off the reel. I wonder if others have
compared measurements of their actual installation with the Handbook table
-- I'd sure like to recoup that elusive "'nother dB."
