Aerial Support Pole
 

Is the aerial support pole made of a specific non conductive metal?

Reason I ask is that I want to experiment with an aerial in my loft
and a copper plumbing pipe is very convenient, also I have the tool to
easily cut it to length.

No... the pole is not part of the equation and is not relevant.
It`ll be fine.

So long as the pole or mast does not pass in between the elements and/or
dipole and/or reflector.

Only applies to vertically polarised, has no effect on horizontally
polarised aerials.

They should be conductive if metallic!

I replaced my flimsy one (alluminium?) with a scaffold pole (steel) for
added strength, since my original one sheared in the wind.

Copper is fairly flexible, but in the loft you will not get strong winds.

Which non-conductive metal do you have in mind?
You may only choose elements know in the Universe and with atomic
numbers below 92.

It certainly does have an effect on hp band iv and v aerials.
On a vp aerial you can usually get by because the cradle with be at a right
angle to the mast and mid mast mounting is then acceptable.
ie this horizontally polarized http://www.wrightsaerials.tv/farn5.html is a
no-no because the mast corrupts the element spacing.

For experimental purposes, an aerial in the loft can be suspended in
position using string from hooks screwed into the woodwork of the
roof.

In fact my loft aerial has been experimental for years. It is
supported at the rear end by a short rod (behind the reflectors),
and at the front end by a piece of green string.

Thank you. It is so easy to get incorrect advise. Aerials are either
fitted to the mast from a rear mounting clamp or with the use of a boom
bar. At no point should the mast be fitted directly to the boom bar of
the aerial.

A very few exceptions are low frequency signal aerials such as Band III
and FM, though it's a compromise on the manufactures part. Also the
only UHF exception that I've seen lately is the Televes Dat75. How
Televes got away with getting it passed as a CAI Standard 1 digital
aerial when the mast passes between the elements is anyones guess.

Strangely enough, the Dat75 is currently th only Standard 1 WideBand
aerial. The other Standard 1 aerial is the Blake DMX10A which is a
group A aerial. Just doesn't figure does it...

I've just swapped a Triax Unix 52A for a Blake DMX10A for a mate of mine who
is well outside the official service area of Crystal Palace.
A bigger aerial was not practical because of mounting limitations, but using
the same masthead amplifier and Philex PF100 cable run it has improved
signal quality on all MUX's and he has rock solid ITV1 at last!

I was sceptical because I recommended the Triax Unix in the first place. The
Blake came from CPC (I think) and was unbranded and much cheaper then the
Unix. It is definitely a DMX10A though.
The size, weight and price difference between a DMX10A and a DAT75 makes
their common CAI standard 1 status all the more amazing!
