Well,
A while ago we had some work done in our garden, this resulted in the removal of a 'purglar'; now, this was all fine except it was supporting my top band antenna I made back here.
I've got round to making a replacement for the antenna today, nothing original - it's an end fed sloping, inductively loaded wire.
There's 54 feet of wire, 20 turns on a bit of tumble dryer vent pipe, then 5 feet to an earth rod (well two actually). Here's the inductor:

and this is the earth arrangement:

Now, I am planning to add several long counterpoise wires, but I haven't done so yet. I connected the antenna to my analyser thingamabob:

or if you prefer return loss:

I've been listening on the WSPR frequency tonight:

It will be a very inefficient antenna and also it has a very narrow bandwidth (like all inductively loaded antennas), but it's clearly hearing signals.
Here's a map after an overnight run:
I also took down the main 4M and 6M antenna today for maintenance, I've put somthing I had at the back of the shed in it's place temporarily, I've also put the 13cm antenna I had lying on my bench in the air:
Here's our two doing what Spaniels do on a beautiful frosty morning earlier today:
Good, egh?
