No, I don't. I have exactly 25 feet. This needs to include any insulaters
of support ropes at the ends, if I use them.

Hi Geoff,

Put up 3 to 5 sections of twinlead (with the wires shorted at both
ends) on each side, fanned out at the far ends across 3 to 5 feet
(looks like a bowtie). Feed at the apex of each triangular half, that
meet in the middle. Choke the cable feed.

2:1 SWR bandwidth should be at least 1 MHz wide.
