Specification of Hughes HX50 terminal. Setting the elevation angle. Update 14 April What is discussed here also applies to HX I had no problem putting the dish together or programming the HX50 modem and pointing at the satellite. I powered off and connected the transmit cable, powered on commissiooned, without touching anything, ten minutes later it was all working well and I was browsing the internet.
It resets to back to zero traffic count and up to fast speed again every 8 hours. I downloaded Mbytes commizsioned Microsoft updates and a couple of hours later was back to full speed again. During the assembly and installation I noted several new features, such as the new mode-matched feed horn and the way it needs to be assembled for polarisation setting.
I draw attention to these points in the further details below. The large square box contained the 1. The cube shaped box contained the 3 axis antenna positioner and the Hughes HX50 modem and the outdoor 2 watt Ku band radio assembly. Put the modem is hughesner cool dry place, away from direct sunlight and sources of heat.
A free flow of cool dry air into commmissioned lower vents either side near the base and out via the vents around the top is important. This low commissipned multi-way cable should stay connected to the co,missioned all of the time. The low voltage DC connector must not be disconnected from the modem while the power is on. If you need to cycle the power, this must be done at the AC mains wall switch. The mains AC power supply module has input intended for – V Hz 2. The commissioned comes in a large square box marked “Fragile” and it needs to be treated as such.
Wash your hands before you hold it. When you remove it take care to lift it and not to scrape the edges. I was rather impressed to see that there were 4 ball rod reference points around the periphery of the curved surface.
I have the impression that this dish is probably good for Ka band operation, provided the reflective metal material under the paint surface is smooth and continuous. There were no part numbers or serial numbers on the dish. The front of the dish has been spray painted with a matt white paint which has a hydrophobic effect.
After heavy dew the surface is covered in tiny droplets. The “matt” aspect is good since it reduces the heating of the feed and RF assembly when the sun reflects at around the time of sun noise events, which occur on several days ocmmissioned spring and autumn and for a few minutes on each day. Try not to touch the front surface.
The 3-axis positioner is a good design, clearly based on many years of experience. There is a strong plastic moulded dome shape which attaches accurately to the back of the dish with proper bolts. I much prefer this to the giant self tapping hugehsnet, as used on some older antennas.
The rear of the plastic dome is angled so as to compensate for the commssioned angle of the dish and to provide a polarisation adjustment plane at hugheset angles to the beam direction.
It is possible to place hughenset inclinometer here, against the commissionedd metal plate, where the two pairs of the 4 polarisation bolts are located. If you don’t have an inclinometer then read about setting elevation angle by measurement. This scale is really good, it is accurate and easy to use and you don’t need a magnifying glass to read it! Loosen the four polarisation bolts and rotate the dish to highesnet the required polarisation adjustment angle. Clockwise, while facing towards the satellite, is positive.
This will lead to some strange appearances, as the entire dish may seem to be almost on its side. Don’t worry, this is correct. Set the polarisation angle accurately – the scale clearly shows 1 degree intervals. If you are operating with a Eutelsat satellite, add 3.

The polarisation has been adjusted to deg anticlockwise. The site is north of the equator and the satellite is in a south-easterly direction.
Before attempting to make an azimuth or elevation angle adjustment, the main axis bolts must be slightly loosened. Some grease on the moving parts won’t do any harm, for example between the top of the canister and the rotating plate, and plenty along on the elevation screw. If your intended elevation angle is between 87 and 90 deg i.
When you are nearing completion of the alignment tighten the very large azimuth axis bolt and then do the final tweaking of the elevation angle last. There are two possible orientations for the U shaped bracket. Use the lower position normally, so that the outer nut is easily accessible with a spanner, while adjusting the elevation. Use the upper position only if you are operating at a very low elevation angle. If you tighten the main elevation axis bolt, remember to loosen it again if you come back to make a further elevation adjustment.
There is no elevation angle scale. Grease on the elevation screw will make adjustment easier, as the weight of the dish is taken by the nuts. The instructions are good. The pipe or pole interface below the 3-axis positioner is the canister which is intended for a vertical pipe, 2.
The minimum height of the top of the pipe is 18 inches above ground level. The pipe should extend 30 inches below ground level into concrete.
The bottom end of the pipe needs to be cut diagonally or to have some metal welded on cojmissioned the side to prevent it rotating in the concrete. Before pouring concrete check you can see the satellite! You can use a locally purchased pipe. Think about elevation angles and visibility of satellite before buying the pole and pouring the concrete. Alternatively, you may use a non-penetrating mount.
If you have a non-penetrating mount follow the assembly instructions carefully.

Some designs involve the lower and upper sets of diagonal braces being joined at the pipe in anticlockwise and clockwise directions to prevent slight pole rotation movement. There is only one hole across through the main feed arm, so no chance of incorrect assembly! It comes with two bolts, washers and nuts for attaching to the round tube of main feed arm. The ends of the rods are flattened. The longer ends go to the reflector.
The power distribution is a compromise, to achieve acceptable gain and sidelobe pattern simultaneously. The throat of this feed horn has three internal mode matching slots machined on the inside which cause cross polarisation performance opposite to that generated by the offset-antenna geometry. The net result is superb cross-pol performance of the complete antenna. The feed horn comes with a spacer section of tapered circular waveguide, attached to the feed horn at a specific angle.

The rear flange rim of the waveguide spacer is marked in two places, at 90 deg to one another, with a single score and a double score marking, 90 degrees apart. The on the feed throat and the single score mark on the rear flange of the spacer must be oriented directly away from the feed arm – regardless of the polarisation required. The feed comes with commisdioned yellow sticker saying “Hazards caused by Electromagnetic fields, Keep away 4 feet 1. This an angled, galvanised steel tube which attaches to the lower edge of the dish.
Its length is suitable for the 1. The feed end of the arm is circular tubing, with two bolt holes. These are good instructions and worth reading. But, on page 10 there is reference hugjesnet a forward yoke which is not used in this instance. Note that the three feed support arms and the outdoor RF unit are not joined by metal to the positioner and mounting pipe behind the dish.
This in my opinion is a good thing as it prevents commssioned earth currents from the antenna location to the modem location travelling via the coax cable. The connection of the coax cable outers and the building earth to a real lightning earth is controversial and possibly hazardous and a qualified hughesnst should be consulted. In buildings using PME the addition of a new earth cable to the real ground may, under fault commissiondd, provide a path for a very high current from the local neighbourhood and thin cables alone, such as the coax outer braids, from the modem to the lightning ground are a fire hazard.
Local oscillator switching is done using a 22 kHz tone from the modem, sent up the coax cable. Attachment of the feed to the OMT requires special attention regarding nominal polarisation setting at the initial assembly. From your service provider determine what is the nominal polarisation you are to receive before your start assembly.
This nominal receive polarisation will be called “horizontal” or “vertical”. You later rotate the entire complete dish by 90 deg either way if Vertical name receive polarisation is require. Then commiszioned the polarisation angle adjustment amount. The polarisation scales on the white BUC yokes read 0 zero deg. The image below shows the top view, looking directly downwards. As shown, the transmit polarisation, from the BUC on the left, is vertical. Receive polarisation is Horizontal.
Remember to attach the feed horn with the directly away from the feed support arm. With the entire dish rotated so that the feed arm is at the bottom centre you are at a Horizontal receive polarisation starting position.
