"This page is all about Where the energy really goes in an antenna system. Will a high SWR blow up my transmitter? ( No, it will not, but POOR TUNING can.) ---The Reflection Section--- The purpose of this section is to explain what happens when un-used energy comes back down the coax from the antenna. "

Here are some simple truths that you probably knew before you got here, but when they are all put together, you will have 7 different things happening.

The goal was simple: Using the autotuner, tune the most number of bands with the highest efficiency on a doublet antenna. Getting the highest efficiency mandates the use of ladder line because SWR loss can be very high using coax on multiband antennas.

VHF and above SWR meter

"This calculator computes the matched line loss for a transmission line using a model calibrated from data for the transmission line types built in to the calculator. It also gives an estimate of the mismatched loss if the mismatch is specified." This model has been recommended by Cebik.
