Well, I converted to ladder line, I'm running 10 ft of RG8 Buryflex to a DX
Engineering Balun feeding 43 ft of 450 ohm ladder line to my 40M dipole. 20
meters is about the same on either this or the coax fed 20M dipole but 40
meters has an infinite SWR. the Yaseu FT1200 tuner won't tune it but the MFJ
998 will but sigs are as weak as on my 20M dipole! 15 & 10 seem fine but
not
much to compare to.. Whats up with 40??Dick NY1E

I'm in a limited space location, I'm looking for a wire antenna to use on
40-10
meters. The handbook says a 40m dipole fed with ladder line will be 2 half
waves in phase on 20, and have 1.8 db gain. My coax fed 20m dipole is 10db
better than my coax fed 40m dipole on 20, will open wire feeders and a tuner
really improve it that much?de Dick NY1E
