Top Band with an End-fed long wire

Post by MrWeetabix »

Been messing about with a new end-fed setup and managed to tune top band last night. Must be the first time in 10 maybe 15 years I've worked the band, so quite happy to be heard across the pond on 5w :-)

Anyone else work the band?

We have a 'good old fashioned' AM net on 1963 kHz every Friday and Sunday evening, 8:30 pm local time. I use entirely homebrew gear and so does Philip G4FBG. Arthur G4BKH uses an elderly Yaesu rig. It's all good fun and we are within about ten miles of each other. Signals are generally s9-ish. After dark I find my signal 'lands' along the south coast and in Ireland at good strength.
TX aerial at all stations is some kind of vertical, mine is a 48-foot fibreglass 'roach pole' type of thing with a wire running up the side and a loading coil about 12 feet from the top. Me and Arthur use Wellbrook loop antennas for receive and Philip uses his vertical.

I find them to be around S6/7 on average down there. I have some copper pipe which I am going to use to drive earth rods in at the base of feed and also on next to where the RF choke is located, which will connect to the SO239 barrel joint between the choke feed and my shack coax. Also bought a role of chicken wire, which I am going to lay across the garden too, with a mind of either going all-in and using them all in combination, or having a play with then, disconnecting/reconnecting to see which method works best.

I have some photos on my phone of the installation, I'll upload them here soon.

It ended up being about 4m short of the ideal length I had researched would suitable for the most usable bands, so the excess is coiled around a piece of Plastic drainpipe at 2.5cm spacing.

I am using the bungee cords to take up any slack greated by the cable expanding/contracting depending on temperature. I may replace this with some sort of counter-weight going forward as I think the rubber in the bungee will perish over time.

This is how it is rigged up, ‘borrowing’ a lampost to the front of the property to suspend the far end.

The 7300 needs to be in emergency tune mode to work on all bands, with the exception of 80m (it refuses to tune). I am hoping that with the addition of the earth rods and/or the chicken wire I will get 80m working. The TS2000 will tune on 80m, but only with less than 20w currently.
