Re: 60cm Dish with Patch vs 3ft dish with offset helix feed



Hi Mike and the amsat-bb group
Using the G3RUH 60 cm dish with the patch feed and a UEK3000
Converter. Usally see the Beacon 4 S-Units above the noise on the
average. Right now around MA-170 am seeing around 6 S-units
above the noise. Oh Yes, There is no Desence.
