What kind of antenna would be used for 2-meters SSB mobile operation?

    Getting back to the original subject ,there IS a difference between the Omniangle (isosceles triangle) and the round or square "halos". The Omniangles are an entirely different design. They are electrically longer than the halos and it is the shape and electrical length that yields a pattern that has a far better omni pattern than halos/squalos. In addition, the halos all seem to suffer from mast radiation and common mode from the coax. The Omniangles suffer from neither.

    I must admit, for VHF "roving" I've tried round loops (halos) and square loops (M2) and also the Ominiangle, and the Omniangle did seem to work better.

    Difference may only be 1-2 dB, but when you're looking for weak signals in the noise, that helps.

    Are they still making the omniangle antennas?

    Universal Radio was the only reseller I've found, and they list all models as discontinued. Par Electronics has a small link at the bottom of the omniangle pages to email for pricing. Guess you'd have to drop them a line if you want one.
