[50mhz] polarization ?

[Steve Grimes]

I just bought a Par OA-50.  It's an omni and 63 reviewers gave it a
5/5 on EHam.  It is horizontal polarization, but it can easily be used
as a base or mobile.  The shape is an isosceles triangle.  Supposedly,
it hears really well and has a low noise level.  Check it out.  Dale
will be happy to answer any questions with a phone call.
