Do you need a balun on you EFHW antenna 49:1 ulun

Does you efhw end fed half wave antenna needs a 1:1 balun common mode choke? possibly it does . especially if your using a 49:1 ulun or 64:1 ulun or a L network what to see why and any end fed wire would benifit here we have a wire on the higher HF bands 10M / 12M 28 MHZ 24/MHZ and CB radio 27 MHZ this will only reduce local noise that the coax is picking up if you have noise that is air born and is being picked up by the antenna itself then your not going to get any improvement but you will reduce interference to neighbours /shack if your line is radiating . Make your own visit trx bench /baluns and good luck.
