You're viewing part of a thread.
Note, important safety tip: you can get closer to this tower without clearly trespassing or jumping fences than most other 50KW broadcast antennas I've encountered. I measured a field strength of over 80V/m a bit outside the tower fence, which is an incredibly strong signal (though still within OSHA limits at the frequency involved).
Resist any temptation to jump the fence and climb the (energized) tower. You'd be electrocuted as soon as you touch it.
Ever since I saw this video by @[email protected], I realized that respect for towers could be life-saving.
@[email protected] there may be a literal pair of smoking boots as the only remaining evidence.
@greem @mattblaze I’ve seen that movie.
@[email protected] @[email protected] The actual line is even better.
@[email protected] @[email protected] Proof that "You don't want to look in there" > "I do not consent to a search"
@[email protected] @[email protected] @[email protected] I’m gleeful to see the absolute best film ever made finally referenced here. Laughing aloud, thanks
@[email protected] Interesting I'm going to do some field tests for interference for a wildlife monitoring radio system & I'm wondering what you used to measure this
@mwhelm For AM, the instruments of choice are the Potomac FIM-41 or PI-4100 (the former being older, analog, and more fun to use, the latter being soulless, digital, and easier to use).
