It's two 6146 in parallel, but they only have 450v on the anodes, so hopefully should last a long time. The aerial is a half wave inverted V dipole, with the ends bent back a little to get in the space. The main support is in the centre - it's a 6metre fiberglass pole, mounted on the gable end of our bungalow at the back. The height at the centre is about 30 feet.

It's only good for 80, as a resonant aerial , but I did strap the co-ax ends together and tuned it against earth , with an AMU, for 160 some years ago.

Yes, it's very nervy climbing up a ladder when you get past a certain age. I managed it about 3 years ago. Not sure I'd want to try now.
