Absolutely nothing. My ISP has a program where I can loop a large file to test. If I tape the Cat5e to the 250' run of cables back to the house the rate drops down to dial up speeds. If I use loose t

The bandwidth comment is correct Eric. I had to swap stubs between CW/SSB contests for 80/75M. Other bands were adequate set in the middle. My initial attempt was CATV RG-59 which arced thru at 1200W
