Motor for terrestrial antenna

[steffan_st]

Planning on motorizing my terrestrial antenna this winter when I switch to digital.

Anyone seen any motors around the net?!?

Maplins do one, item QT40T, ok for light to medium loads, I suppose (45kg).

Otherwise check out amateur radio sites for more heavyweight rotors.

Nevada do a range (some pretty expensive though) -

Don't do what I did when running the cable - leave enough slack for a 360 degree turn to avoid stretching it !

Get out and turn it. Dont forget you also have to install two antennas, one for Horizontal and one for vertical polarisations.

If it is anything like the UK, the vast majority of transmitters are horizontally polarised, the vertical ones being very low power, for local infill only.

Sounds like a job for a wiper motor to me

Didn't think of that!

Not a bad idea,I love homebrewed stuff!

Thank's all for your answers,I have to think about this for a couple of weeks and see what channels will be available in my part of Sweden.

Guess I can get the Danish channels with a sensitive receiver down here ,we'll see...

That's Maplins for you. Item no. taken from their latest catalogue, no trace of it online. Even 'Antenna Rotator' (name of said item in catalogue)) doesn't yield a result.

NB Ithink it's the same as the cheaper one at Nevada.

Hallow Stefan,
I've a motorized terrestrial antenna, remote and local controlled, two outputs, 35db gain,bought from Varna Bulgaria - 24 bg leva(abb.16$). Works well.
Regards, Petko

Which part of Sweden ?

Someone here should be able to pinpoint the transmitters that are local to you to narrow down the choices of equipment you may need.

I'm in the south east,the Danish island Bornholm is about 150 km:s south from my location.

2 antenna rotators at bottom of this cpc page:

Hooray for cpc, which recently "rationalised" stock, but still seems to have most things.

Thanks,looks interesting!

Saw this thread when searching another one.
In northern Sweden you can actually use these rotators for dishes because el. is almost the same on astra-sirius. Having said that a lot of foreigners sell these in their stores, I think you know what stores I mean.
Remembering correctly I saw one for 300kr a few years ago, this one was imported from Germany. A friend of mine has one and it operates good even in -25 celcius but sounded strange from the controller.

Go to www.conrad.de and search for rotor.
They have one for 40Euro
