    Orbitron 10 ft- actuator attachment

    It's true but why should it block the centre hole for water drainage.May be then it should go between the two hub plate.

    Orbitron 10 ft- actuator attachment

    I'll put it on pole first to see if the bar fits somewhere. But I'll have to unscrew at least two bolts to put across.This may deform the dish.I don't know if it will fit between the elevation bar when I put it where I mentioned. As for the printing plates, they perform quite well. My dish was...

    Orbitron 10 ft- actuator attachment

    I made an earlier post regarding a missing intermediate plate for a new orbiton 10 ft .I did not get the plate but I cut one out of alu sheet and assembled the dish. I have one problem now : How to fix the actuator to the dish. I found only one black square rod among the parts. I do not know...

    Intermediate plate for Orbitron 10 foot

    Thank you guys. If I do not get one I'll try cut one from a metal sheet. I want at least the dimensions.The manual says " 9/16" x 2 1/4" fingers". If it is same dimension as top plate,then it will be easier. it also says "There is also a thinner 10 1/2" diameter silver plate" But 10.5 in = 26.7...

    Intermediate plate for Orbitron 10 foot

    I recently got hold of a new Orbitron 10' mesh. Some hardware are missing. The most important is the intermediate hub plate. I know it will be difficult to get here. Can somebody give the dimensions for this plate. This is what I got from the manual I've downloaded from our forum: The...

    c-band multi-feed sat dish

    Bravo Agers. Could we get a front view pic? Are the two sats Telstar 10 and PAS 7/10? I will do same when my dish up.

    Wire size for 24" actuator

    Now I understand. A longer actuator will track with better precision.

    Wire size for 24" actuator

    Thank you. it will be 40 ft only. I'll try to find a suitable cable. I find it ugly to run two cables, one big and one small up to the dish.

    Wire size for 24" actuator

    Trying to drive a 24" inch actuator on my 12 ft mesh. The only four wires cable I manage to get is a Manhattan M4662 20AWG. will this 20 AWG be enough to withstand the max current?

    How critical is a dish focal length

    plastic screws threaded 3/4 inch. f/d on scaler ring adjusted to around 0.37. I get some 6% quality improvement on a a known transponder.I will do further testing. May be with depth of screw. I discovered something that needs adjust. A satellite half way on the left needed a lower elevation to...

    Merci. Already remove everything. Three plastic screws threaded. wait tomorrow to get exact length metallic screw. Night has fallen here and mosquitoes have risen

    How critical is a dish focal length

    Thank you guys. I'll adjust the screws and report back. Yes it's true.I got the dish without mesh and I put thin alu sheet (those used in printing). In fact I copied it from a friend who used the same material. So focal length is around 1/4" inside ( from the mouth of the guide). So it is...

    How critical is a dish focal length

    I don't know if you understand me. If you look at the first pic you'll see the original adjustable screws which are not present in the LNB pic. I've already made three new plastic screws which I intend to put on. The dish is old , may be 20 years or more but is not the scaler ring adjustment...

    How critical is a dish focal length

    I refurbished a 12 ft C band dish and calculate its focal length to be 49.85 inches. After assembling all three LNB supporting struts to the "horse shoe", I find the distance from centre of dish to be 50.25 inches. In its original design there were 3 plastic screws( 1 inch) to adjust the focal...

    Will teflon affect signal on linear satellites

    I have the Teflon dielectric plate in my LNB. Will it affect signal level when moving from Circular sat to linear ones. If yes by how much?

    Pole length for 11 ft dish

    Thank you man,I'll lower it completely to work on. I will check if lnb is accesible because it is a prime focus.

    Pole length for 11 ft dish

    Thanks . I've got no intention to track the arc with this heavy fiberglass. The pole is roof mounted. It will be fixed to one satellite. My concern is with accessing the lnb easily.

    Pole length for 11 ft dish

    I recently got a prodelin 11 ft dish with a very good pole and mount but the pole is only 36 inches. I will be on fix satellite at around 63 deg elevation at most I can change idea and go down to another sat at 56 deg. I do not mind the dish is lower but will it be possible for me to acess the...

    Dish azimuth

    I finally got the answer from Eric Johnson telling me that there are some errors in magnetic deviation for some parts of the world in his program. So that accounts for this. Thanks to all

    Dish azimuth

    I am in Mauritius (indian Ocean) and want to point my 12 ft c band to true North. I have some problems with Mauritius: Satellite map, lat and long, and satellite TV dish pointing in Mauritius It gives the following: Latitude = -20.1436, Longitude = 57.5491 Lat = 20 degrees, 8.6 minutes South...
