[TowerTalk] Fwd: F-connectors

[charlie carroll]

Measuring at 50 MHz, the difference in loss / 100 feet is about 0.4dB 
for the 2 cables.  Make it a 1/4 section at 80 meters and you're near 
0.1 dB difference in loss.  Good luck making meaningful measurements.

>>> It doesn’t take much of a nick either to later find a build-up of rust particles when opening up an unsealed F connector.  For the last two years, I've been purchasing 1,000 ft rolls of Belden 1829BC from Markertek.   Price is approx. USD $150 per roll.  It's gel-flooded RG6 with a solid copper inner conductor and works well with old and new SNS compression connectors like the new PPC EX6XLSPlus I mentioned earlier.  A solid copper inner has the added advantage of lower voltage drop when used in DC power-passing applications on extended runs.
