Thank you - that makes some sense!

Is this different to the meter on the CB radio itself? Mine has a meter with a single needle, but two gauges - one labelled signal, the other power.

And I've been reading about tuning the antenna - but what is there to tune? Does this mean the direction it is pointing in? I have a car-mounted whip antenna - and I can adjust the angle it points at, but not much else. I've only tried it perpendicular to the car roof.

Do Squelch and RF Gain have a role (I have knobs for these on the radio).

Apologies for the newbie questions!
