Re: Bit of practical today


Did the practical course explain why a choke balun is a good idea if you are feeding a balanced antenna with unbalancd feeder??

I thought not. emoticon

I really must get my ass in gear and sort out the foundation exam.

Re: Bit of practical today


no just that a balun was a choke and would help with tvi and rf coming back down the braid, i did ask why the diferent baluns, ie, 4:1, 1:1 ect but they said they didnt want to confuse me as they were teachin me to pass the foundation and to just take that on board first,, lol

You also get a different call sign, I mean, a new call AND 50 watts how can you not take it? There may be more but there the ones I know anyway, you would learn new stuff to!
