Should an end fed long wire 132ft tune up on top band??

Yes with an ATU. As a rough quarter-wave.

Edit ... Against earth BTW

Can the 9:1 UNUN ground side be connected to a tree??

For instance, a very short lead with a eyelet on the end coming off the ground/earth side.

The eyelet can then be attached directly to the tree by a non coated screw effectively grounding it to the tree.

The tree, being alive, has an extensive root system

Would this work as an effective earth for my long wire??

As a tree is mainly constructed of "wood", quite a reasonable insulator, in its "dry" form, and any conduction to earth would therefore be via inbuilt "moisture"...... and taking into account the fact water is actualy quite a poor conductor of electrical current, in its purest form, its "conductivity" being reliant on various disolved impurities and salts...... I would suspect it would be about as effective as a short earth "spike" pushed into a plant pot!
Add to that the fact that the tree itself might not take to kindly to having "currents" shoved through it, you may well end up with a dead piece of wood, as oposed to a live one!

Unless it's a copper birch, of course.

Surely "Silver Birch" would be better!

You're both wrong, Golden Robinia is best

On a more serious note, if you want to use a tree as an antenna, take a look here...

Another 'branch' to the hobby? (sorry, had to be said!)

In 1904, it would also beg the question, as I did'nt see it mentioned. at what frequecies these "experiments" were successful!
I suspect VLF spark based TX equipment?, and suitable "Coherer" based RX tuned devices?
The US Navy has done ELF experiments, using the sea as a transmision medium, with two large submerged "plates" supplied with ELF RF energy, effectively energising the separating salt water as a transmission antenna to broadcast to submarines!
However, I serioulsy doubt it would be awfuly effective above a certain critical MUF!

A more modern example http://w5jgv.com/tree_antenna/

Is MUF = Maximum Usable Foliage

And would conifers "fire" straight up, whereas broad leafed oaks, would give a lower angle to the horizon?

You could always remove all the branches and tip it on its side.... Now that would be a 'BEAM' antenna

Or am I bark-ing up the wrong tree

Oh please, 'leaf' me alone... (gawd they get worse)

Ok folks, I get it!

Can anyone tell me if a 'counterpoise' for my 132ft long wire has to be laid out like the long wire or can I get another 132ft of wire and wrap it round a former, like a coil?

Sorry. My 'wind-up' alarm has just gone off, what with the tree and all.

Is this just for Top Band; and will the counterpoise be elevated?
