Anyone have a way of measuring the varying efficiencies of the
following? Let's say 5 to 20 MHz frequency range.

This would be the base number for comparison, assign it a one:

a: Straight connection of a random long wire antenna


The others...

b: The same long wire connected through a television (75/300 ohm variety)

c: Same antenna with a 9:1 ratio transformer

I'm assuming everything else remaining the same. I'm interested in the
variation, shown ratio wise, between the above. Are there any handy
online calculators for this?


The problem is that the variations come from characteristics (like
properties of materials and the physical construction) that are easier
to measure than to model. Buzzword: Network Analyzer.
