Looking at possibilities for 6m mobile antennas to use with Ic-706 (original).

Currently using a Larsen NMO 50 tuned to the FM portion of band.  Okay performance, SWR <2:1 w/ BW ~600kHz.  For /R work it seems fine, but if I want to go down to the SSB portion I have another whip cut longer making things inconvienient as I have to pull over, switch whips etc.

Has anyone found a good compromise 6m mobile that would give a little wider BW for SSB and FM ops?
Are the Comet/Diamond 'multiband' types very good on 6m? ProAm hamstick for 6m any good? Tuner?  Suggestions...?

Thanks

     Hello, I saw your question regarding six meter
antennas for mobile use.  I use a simple 54 inch whip
(with screw mount)onto a square Larsen Mag mount.
I have found the SWR is flat for the FM portion but
works very well on the CW/SSB portions.
With no loading coil I have no loss of power from my
Yaesu FT-690R Mark II multi-mode six meter transceiver.

I've been using a 1/4 wavelength whip on a Larsen 150
on a magmount. Good range on 6m repeaters around here.
Tunes the SSB part of 6m also but this is obviously
not a DX performer. A *big* advantage for me is that
the combination also works well as 5/8 wavelength on 2m.

The Hustler 54" MO-1 mast is resonant on 6m by itself, and because of the large diameter of the radiator is broad-banded enough to cover the entire band.

Their SF-2 2-meter 5.8 wave whip also works well on 6m, as will almost any 2-meter 5/8 wave, although not all will cover the entire band.
