Surprisingly this bird hears very well. About 30 watts of uplink power into 2x10 elements horizontally polarized stacked yagi for 2M was about enough.
Hummh... About 2100 Watts EIRP. Yep, it should hear that nicely...
Not that much... Probably only half of this as the antenna only has a gain of 13.8 dbi.
Though in the western pacific, this is understandable to get over all the terestrial QRM from unlicensed operations on 2 meters..
Exactly to the point. At times, these unlicensed operations simple override our signal, if low TX power is used. Its much more easier on 435 MHz or 1268 MHz here, where some 10-15 watts of TX power is more than sufficient.
