any thoughts on which is the better option?
I just got my starduster up, around 35' to the feedpoint.
without the low pass filter I have a flat swr from 1-40, with it installed my swr jumps to 1.3 on 1 and 1.5 on 40.
I'm assuming it's because the lpf is 52 ohms instead of 50, or am I wrong?
the filter is a 20 year old drake with 80 db atten. minimum above 47 mhz. good for 1000W, but I'll never push more than 80, if that.
even without it I haven't seen any signs of tvi. my computer speakers remain quiet on both am and ssb. they usually pick up people modulating while driving past.
