Longest rod is 49cm. So that's VHF Channel 7 and above...
I could pick up FM broadcasts pretty good though! Even CB!! Despite the fact those bands are out of range for this antenna.
All in all I wouldn't use this one for television TX.
I have aluminum pipes from a Radio Shack antenna kit that're about 1.5cm in diameter. Are those OK for making a 50ohm dipole for Channel 3 TX? 50ohm because that's what my
RF amplifier expects.
I use an RF amplifier because the signal from my agile modulator is too low. The amp generates awful harmonics. How do I filter it? Can't find appropriate RF filters from Digi-Key or Mini-Circuits for a reasonable price.
