Antenna Size So I was reading the above thread, and loved the explanation at the end. But my remaining question on Antenna Size is that..Okay I get why for low frequencies we *need* to have bigger antenna, so how it is that people like Hams transmit on lower frequency, long wavelength channels? Do they literally build these massive antenna? Also *why* is it that short wavelength, higher frequencies can get away with short antenna? Is it about the resistance? Can sw waves be "Pushed out" easier with the low resistance, unlike longer waves? My last question is related as well... *why* is it that smaller waves with high frequency are better at atmospheric and building penetration than the lowers? I know that frequencies in the VHF and ULF + range are much better at breaking through the ionosphere and making their way outward to space. What is it about the lower frequencies than makes this impossible for them? Pre-Thanks everyone for your time!
