You've touched on several points.
1. ANTENNA DOWN
Leaving the antenna down *is* stressful to the transmitter. But typically
the manufacturer over designs it to withstand the abuse.
2. ANTENNA VOLUME
Antenna theory is an UGLY course that I successfully avoided. I only skimmed
the surface thankful

Thanks. Very interesting.

Why doesn't leaving the antenna down on your Tx damage the Tx then? Is it
just not
OK.
SWR is short for Standing Wave Ratio. Which is the ratio of forward to
reflected power in an antenna system, and affects the efficiency of the
antenna.
Ideally, a tranmitter will dump it's output into an antenna and it is
radiated out to the world. The length of an antenna is dependant on

Answer: Yes and no
In our world of R/C modeling, the diameter of the antenna wire matters
little. But, in theory, a larger diameter wire will have a more constant
SWR over a given frequency spread.
