Hi All,
I've bought an American motorhome and the aerial is decidedly odd
looking. It is omnidirectional, manually rotated and with a masthead
amp included. The question is, will this work in UK and Europe for
digital pictures?

My reason for asking is that it is currently faulty and I'm wondering
if it is worthwhile fixing. The other thing which occurred to me was
to replace the flat plates with two bits of UK aerial to see if that
helps.

I've attached a picture for which I apologize, but trying to describe
it in words would take up more bandwidth than the size of the picture!

The picture needs to be posted on a file sharing site or somewhere before we
can see it.

Your aerial isn't omnidirectional (you can rotate it). Most of these things
are a combined VHF/UHF, generally with two downleads. Some of them have
vertical elements as well as horizontal. Some of them have a third cable for
FM radio. For UK use it is unneccessarily cumbersome, although a replacement
might not look as nice!

The only thing that goes wrong with these is the built in amplifier. Are you
powering it correctly? There's often a power unit in a cupboard with LEDs on
it. Others take 12V to the amp directly (not thro the coax), in which case
there'll be a switch with a LED somewhere.

It isn't impossible to change the amp for a UK one. Use a low gain one.
Power via coax and use a line power injector to add 12V to the coax. Use a
500mA inline fuse.

If you lift the aerial off the van be careful with the seal. If it's
perished you have a problem.

Am I the only one who can see it? It simply looks like a horizontal folded dipole of indeterminate size, with something in the middle (presumably a preamp?), and mounted on a short pole. If it is a preamp, and you aren't powering it, you won't get any reception.
