Just for practice, I'd like to know your numbers.
that three foot stub of 300 ohm line seems like it would impose alot of low impedance inductance in shunt with the feed Sure Jerry, I was hoping someone would check it. Eznec says at 3.8 MHZ a 100' dipole about 35' up over average ground is 17-j343. .126 lambda or 32.7' of 300 ohm line transforms to 7.5-j17.6. .011 lambda shorted stub or 2.9' connected at the 7.5-j17.6 point gives 50-j0. The ..011 lambda stub is .874 uh at 3.8 MHZ . This is according to Mr. Smith and his chart. 73 Gary N4AST |
