They ripped that out of the Naval Radar Engineers Handbook
(see https://ewhdbks.mugu.navy.mil/contents.htm)
There's a chapter on jamming, and I like the example that starts off like
this:
"Assume that a 5 GHz radar has a 70 dBm signal fed through a 5 dB
loss transmission line to an antenna that has 45 dB gain."
So the radio output is 10 kilowatts and the entire system has an
EIRP of 102 Megawatts. Nice. And the FCC is worried about my base
station with an EIRP of 200 milliwatts :-)
BTW: a simple dipole is easier to build and has better gain than an alford
