Hi Guys,

Thanks for your good suggestions.

The first thing to understand is that for the most part the CB 5/8, 6/8,
7/8
antennas have nothing to do with the actual height. Manufacturers started
claiming these lengths because the CBers believe(d) longer is better

The physical length of those antennas available over here are 6.5m, 9.1m and
9.5m. So any height between 6.5m and 9.5m would be possible.
It is an alternative for going to a DIY store to get aluminum tubing.

The other problem is if the reactive component gets too far for your
tuner to handle, but without knowing the tuning range of your tuner,
that's hard to know.

My remote ATU (Pi matching) has an inductance range from 0 to 63uH and the
capacitance ranges from 0 to 6300pF
