[70cm] Contacts on 432 MHz

[melum at alaska.net]

Effective radiated power, referrenced to isotropic.  EIRP
Antenna gain factor times power at the antenna. 

On 432 I have about 1190w at the feed, and 30dBi gain = 1.1 MW
On 2304,  96w at feed, and 44dBi gain = 2.6 MW

Interesting, huh?

Calculations compliments of VK3UM calculator.
