[amsat-bb] Re: Circular polarization

[Mark L. Hammond]

Hi David,

Here is my advice:

If you choose circular, you really need to be able to switch between RHCP and LHCP.  If you are fixed on only one polarity, you are worse off then just using vertical (or horizontal).

So, if you cannot switch, I suggest vertical (or horizontal if you do SSB local/DX).
