[TowerTalk] HAARP Lunar Echoes

[W7CE]

> Amazing what you can do with 3.6 MILLION watts.....wow.

According to the HAARP website, the 180 crossed dipoles are spread out over 
22.6 acres.  Their online gain calculator indicates that the gain is 29.1 dB 
at 7.4 MHz resulting in 94.6 dBW in the center of the beam.  That is 2,884 
megawatts ERP!  I suspect that if they had that kind of power on 2M, we 
could copy them Q5 on a 2M mobile antenna.  My rough calculations indicate 
that with 1500W PEP it would take 65536 (2^16) 18-element 2M yagis to get 
that kind of ERP.
