[amsat-bb] Re: Horizontal Polarized Antenna

[Sion Chow Q. C. (9W2QC)]

Dear All,

Thank you for all the replies regarding this subject.  By mounting the
antennas horizontally will save me a lot of trouble, so I guess this is the
way I will go.

Once again, thank you for all the replies, it is really appreciated and my
apologies for not getting back to each message individually.

73,
Sion Chow Q. C.,
9W2QC.
