Not really. I have a 500-watter 5 miles away that still gives my MFJ 259 fits. It is on 1550 KHz, which may be part of the problem. Makes me wonder whether W8LRL, who is about the same distance from

The high pass filter will transform any impedance other than 50 ohms to a different impedance. Thus doing the above downgrades your 259 to a very expensive VSWR meter (not an impedance meter). If yo
