Tom Herman discussed the signal connection between transceiver and antenna.
Coaxial cable is widely used, but comes in a variety of sizes and quality.
Tom suggested looking for quality shielding - the weave of wire shold be tight,
possibly with a foiil wrap underneath. The diameter of the cable affects
the signal loss in the cable which is generally measured as dB per 100 feet
and increases as frequency is increased..
Open-wire line/Parallel-conductor line/Ladder line is an alternative
transmission line with less lose than coax. There are different concerns when
working with open-wire line, such as keeping the line away from metal like gutters.
Tom also emphasized the importance of keeping water out of coax.
The meeting adjourned at 8:38 PM. There were at least 21 people attending.
