Which dish to buy???

***Oily*** · 28-12-2005

Which deal is the best?
1 x 88cm Triax TD88 Anthracite Satellite Dish ( 85 x 95 cm )
1 x Moteck 2100A Motor With DiseqC 1.2 And GO TO X ( USALS)
1 x Maximum Universal Single LNB 0.3 db
1 x High Quality Steel Wall Mount
1 x Screw set with screws, washers and dowels
1 x 25 metre high quality coaxial cable with 2 F-Plugs
for only £95+£14

Or this one:
1.Triax TD88 90cm dish,
1.Triax polar mount
1.Triax 0.3dB LNB
1.10-inch actuator for £124.95+£15

What does a actuator/polar mount do?I've done a search but its as clear as mud!

The first deal appears the better - Decent bolts/plugs can be a sod to find if you have no trade contacts, or so i found (this was prior to the days of Ebay

)

By polar mount, they are referring to a type of dish mount that when the dish is moved left/right it automatically decreases/increases the elevation setting to follow the arc in which satellites `live` - known as the Clarke belt. The actuator is a piston like device which retracts/pushes an arm to move the dish.

I belive that such devices are not compatible with DiseqC 1.2, as back in the day it was neccesary to trun a seperate `doorbell` style cable to the dish to power the motor - DiseqC 1.2 uses the co-ax cable.

Ahhh, right, now this is going to count as one of your two questions for today!

The first option is good. It's what I have, so I'm not shittin' you.
Excellent starter kit at a realistic price. You won't be dissappointed. Motor is as good as you can get for dishes under 1M, and the dish is right up there too.

Can't comment on the mount or cable obviously. Just take care to fix securely AND get the motor-mount pole EXACTLY vertical.

You shouldn't bother yourself with polar mounts and actuators at this stage IMHO.

Was just going to point you to this Bgonastick,beat me to it!!

***BGonaSTICK*** · 28-12-2005

The polar mount is sort of a specially constructed swivel joint which forces the actual dish to follow the satellite arc in the sky, and the actualtor is a motor-driven piston if you like to actually drive the dish side to side on the joint.

Sorry, that was awful English but hopefully you'll get it.

I was thinking about making my own mount at work out of some box section and flat plate,this is the mount you get with the first kit
Ebay

So,how does the dish follow the satellite arc if it hasn't got one of these 'polar joints' fitted?

***BGonaSTICK*** · 28-12-2005

The geometry is all built into the motor body and driving mechanics. Nice and simple.

I'm sure your mount will be infinitely better if you can weld. Dip it or paint it and it should last forever. Over engineer rather that under. Do it in steel.

The vertical pole must be round tubular section for the motor to mount correctly. Nice thick wall, or the clamps will crush it. 2" to 3" dia.

It does`nt! You need either this set up or a `horizon to horizon` mount (such as you get with a DiseqC 1.2 system) This is like a Polar mount with a driving motor in built so it just looks less Heath Robinson. That mount looks ok but you would need to be handy with a drill, as there is no adjustment to compensate if you didnt get the holes drilled dead straight

Just bought option no.1

Now to make my mount when i get back to work.
Cheers guys

Will do

***BGonaSTICK*** · 28-12-2005

Cool. Make sure the vertical part of the pole is far enough away from the wall, or your dish will foul on full tilt. Copy the dims from a good quality one. 12 - 18 ins offset is about right.

Cheers,wonder if there are any mount diagrams on the net?Will have a search.

You really need "T & K" brackets with a length of scaffold pole between. The "T & K" brackets allow you the get your pole dead upright. Do a google for the brackets or look at the picture that "Rolfw" quite often posts of a set up.
That mount you posted is too flexible for use with a motor.

Thats what i thought,have plenty of steel angle at work.

edd173 · 28-12-2005

Just a thought, i do have some T&K brackets - they are old, but have never been installed, so have a little surface rust where they sat in my garage, but nothing that wouldnt rub off. Email address removed if interested.

***BGonaSTICK*** · 28-12-2005

Make your own T and K out of the angle then

Thanks for the offer edd but i think it will cost me more in postage than it will to make some
