45 cm Dish. Any good?

Postby Serviceman Dave » Sat Oct 10, 2015 8:00 pm

Hi all, I have a friend who wants to get a 45cm dish to carry in his small van. Are they big enough or will a bit of light rain upset reception. Are they trickier to adjust? David

I have used a small portable dish in my LT35 2 berth for the last two years with no problem. It is easily set up using a compass and the satelite finder. I connect the lead to the skybox decoder and turn the volume up high, then can easily line up the dish by hand listening for the sound from TV, then fine tune with the satelite finder to get strongest signal. Gives a good strong signal, have not experienced rain fade at all although can't remember being away in really severe rain.

I use a small dish. For a while I had two LNBs so could watch D1 and D2. I can line mine up just as fast as most people I see with roof mounted dishes.

Yes but slightly more susceptible to rain fade. Normal rain will have little effect.

Easier than a larger one.

Any tips on lining them up?
I finally put mine together today, but didn't manage to make the "sensor facing 8 O'clock" and "slowly move through NW quarter" give me any useable signal (in 30 mins before the guests arrived)

My friend bought the 45 cm dish on Trade me & I set it up outside the workshop door & got a pic. no trouble after changing the box to the correct LO frequency. Moved the test TV so I could see it & peaked on bar graph after using info button. Didn't need to use signal strength meter. Far less critical to set up than the standard house dish. After that I played with a even smaller dish (Ihug internet ?) Fitted standard LNB & to my surprise works 100pc so far. Didn't bother getting out of bed during the electrical storm Sun. night to see.

I have this guide printed off and carry it in the vehicle http://www.dishtv.co.nz/images/stories/Help_Files/Countrywide%20Alignment%20Guide%20for%20Optus%20D1.pdf . You need one of those cheap $20 plastic "hiker" compasses from Burnsco or a camping shop to line the dish up to roughly 318 degrees magnetic, then set the elevation to around 44 degrees and you should be very close to the mark.
