I have a 160 meter horiz. Loop 530 feet around. with a 4;1 balun the swr is 1;1 on 1.8 MHz and 3.5 swr on 1.950 . With a 9;1 balun I cant tune above 1.855 . WHAT balun do I need to have low swr at 1.9 MHz ? [ tuner will not tune above 3;1 swr . baluns are at the antenna feed point] . thanks.

Ok with no being said about wraping rg-58 with foil. what good is the foil shield in the Lmr cables or is it just advertiser hype ?
