    For local contacts the antenna polarization definitely plays an important role. However, for "skip" propagation, such does not make any real difference. Back when the Collins technicians were playing games on 11-meters, there was a LOT of "skip" activity on CB Channel 19. Local communications disruption was only a small percentage of the real effect of 200,000-watts e.r.p.

    Considering that 3-watts output was the average for 5-watts input, the e.r.p. calculates to a 48.24 dB increase over a typical CB transmission using a ground plane antenna.

    I'm not against the change in regulations or specs. Just call it what it is.

    Ah...... excellent point, you are quite right regarding ionospheric propagation vs ground wave. You are quite perceptive.

    48.24 db? You obviously don't do log calculations in your head like The Count! But that's ok, this time.
