Will NIASAT service work on a 89cm dish? How about a 475 foot cable run? This summer we attempted to sync our NIASAT service on an 89cm dish and we were successful. We doubted whether either dish would isolate TX and RX polarities properly, but the 89cm dish passed with flying colors (35 dB ISO – 28dB is required).
We tried a 15 foot cable run and we were pleased to see the up and down receive and transmit SNRs (C/N) were more than acceptable. The power was great and the power pad for heavy weather was even better (power pad is the point between operating and max compression). Again this was on a 89 cm dish. So next we tried 60 feet and 100 feet. The results – as seen in figure 1 – were superb. The signal was great and the power pad for weather was still great.
Now we figured we would try to push the limits by adding several more different lengths of cable. So we jumped up to 250 feet, which should have been pushing the limit. The 89cm came into the network and the signal was very good. I was surprised that we still had 5 dB of power pad.
So we tried 375 feet, which is crazy on any L-band cable system. We switched the cable run and to our disbelief it came into the network and the signal quality was solid overall. Honestly, we were surprised it even was able to acquire into the network with such a long cable run. Then we tried 450 feet and it worked as well! Now we would never recommend using 450 feet of cable, but we were also amazed at the signal quality on the RX and TX. There was a drop in the power pad for weather, but otherwise the system worked great.
During the following week, we decided to try and test a .74 meter (74cm) Ku-band dish reflector. This is definitely an untested system on our network. To give you a frame of reference, it is the style of dish that you’d see receiving DirecTV or Dish network signals. Looks kind of like a potato chip.
After a few movements using a satellite meter, we found Horizons -1 at 127 degrees longitude. So we hooked up one of our X3 iDirect modems and to our surprise, we had a solid transmit! After a little fine tuning on the dish it came into our network with 30 dB of Isolation (28 or better is required).
The Transmit (TX) was a hair weaker than on a larger dish. Other than the weaker TX signal, the values were very comparable to a larger dish. I would not recommend this dish for a customer that lives in a heavy storm area (e.g., rain, snow, hail, etc.). However, here in Fresno we’re fortunate, with very few days involving heavy storms and we receive very little rainfall.
In conclusion, if you need a small flexible solution for Internet connectivity, the 74cm dish will work. We recommend a short cable run and in the least a 3 watt BUC (see figure 2).
