Built the dipole antenna from some plain copper wire, two insulators and an MFJ-913 4:1 balun. I mounted it on my existing pole with a short run of RG-58 coax down to the shack. Its resonance though is around 1 MHz below what it needs to be so when the weather is better I'll trim the wires a little shorter and re-measure. I'll probably have it at around 2.5:1 SWR. Looks like 40m and 15m will be its best bands but let's see after it is trimmed. I have an ATU to match the impedance.
