RE: DIelectric Loading of Helical Antennas REPLY to REPLY



Rick,
I think you mean 1.2Ghz UPlink. Good question. There is no question that the
70cm receiving antenna on AO40 has a much wider beam width then the L band.
As a result the L band like squints of say <15 degrees, while it is easy to
work the bird at angels up to the 40-60 degree range. (side lobes) on 70 cm.

If you don't mind one more question, Gunther, at apogee, what have you found
to be the maximum usable squint when using the L1 receiver?

Thanks again (I'm now inspired to try this myself)!

73,

Rick, KG6IAL
