[TowerTalk] Losses in parallel coax

[Mike Fahmie]

Whether we talk in HF or UHF, the main point that I was trying to make was that when the system impedance changes, so do the preconceptions that were based on the earlier scenario.

Mike,

Exactly the opposite is true -- below at least 300 MHz, loss in 
transmission lines is ALL I squared R. Dielectric loss doesn't begin to 
be significant until you're well into the UHF region.
