So, evil bay provides me with a 4:1 balun for the middle of my planned windom, but there are some stumbling blocks.

there is no way to attach the balun to a pole, and call me Mr Paraniod, but just tieing the wires off to the bolts & wingnuts looks a little flimsy.....

so Worzel Gummage thinking head on!!

here's the balun as it arrived



front off and resting on a nice sheet of polypropylene (yes its a cutting board... £1 from the cheapo shop)



cut the board in 4 with a jig saw to get a double thickness.

one wee thing.... as you cut with a jigsaw it heats up, so the polyprop heals up again behind the blade, but at least it snaps along the line!!



now, holes.....

2 above and two below for the U bolts which will hold it to the pole, and two under the wingnuts. My idea is that the two layers of polyprop will act like the cord grip in a plug and take all the tension off the balun case......

(sorry, nighmare with pic hosting!)

then two screws through the support holes in the balun case to the back board and all assembled (with a couple of dummy wires, just for looks.......)


if tomorrow is dry I might get a chance to take things further......
