Nimiq 1 vs Nimiq 6, signal reports

[tbird460nepa]

ok thank you very much. i guess i'll have to try a re-aim and if nothing else i have a superdish i can try.... i'll let you know how it goes when i figure out when i'll attempt this as its been flirting with 100 degrees for a couple days here...to hot to be out in the sun for me! maybe tomorrow night....?

According to the link above, they also list Nimiq6. When you switch to the footprint for Nimiq6 one line goes about 50 -60 miles north of Phila., is this signal representation for a 18" dish?

In other words I don't see a degrading set of signal lines with decremented eirp levels. Is the line represented above a ABSOLUTE signal cutoff point?

Only one way to know for sure and that is test it.

Nothing in the world of RF transmitting is 100% perfect.

If you were to look at the antenna on the Nimiq 6 satellite you would wonder "What the heck?" as it would look like a vague outline of Canada, this is its shield, the actual antennas are little stubs about 2.5 centimeter's long, these are the transmit antennas, the shield keeps the signal out of the unwanted areas.

Now this is tested on paper, and somewhat in the lab before it goes up in space, but you can't test it's total effectiveness at 22,500 miles, so there may be spillover and areas that may or may-not get the correct signals, or desired signal levels.

The projected footprint for this satellite is based on the Nimiq 4 foot print, to get an actual reading and corrected foot print would require some very tedious ground work with a lot of field measurements.

They more then likely don't have the cash or time to do this, so it's best guess on paper, and a few signal reports from installers.

If the shielding worked as designed, then the signal would stop right at the US Canadian border. but it doesn't, and there is spill over, how far this spill over goes is best guess, as Bell doesn't send trucks into the US to do the measurements.


And in some cases there is an unwanted signal bounce off the shield, this could be picked up in areas far from the designed footprint, were? only time will tell.

0 Q in Ft=Laud., Fl
I lost the beaver

Today (Friday) I managed to scan and find a few here on the PA-MD border. I haven't made a list (but will). I got a bunch of the Dv channels; maybe all of the Venus (all dicks-all the time) channels.

The sig level is pretty low. It seems that 12428 is the strongest. No actual reception yet.

Located 200 miles southwest of Chicago I have Q=0 on all N6 transponders. What's interesting is I have a lock on all N4 transponders with a Q of 56 to 72 using my 36"X39" offset dish. The N6 footprint is definitely much tighter.
Checking with a couple of snowbirds one a hundred miles north of me with a 36" dish and the other 60 miles east of me with a 6ft dish. Both have Bev subs with Bev stbs. They also have Q=0 on all N6 transponders. So, the footprint cutoff appears to be very sharp.
If you would like to get info on N6 with pictures showing antennas and reflectors go to ssloral(dot)com. Checkout the 1300 system. Just follow the links.

Heres a good link to a general of the footprint.....

I'm near Sioux Falls South Dakota and I can get 55% quality on a 39 inch dish for 82. I noticed that my quality on 91 is 0 now though.

Last week the Nimiq1 Veb sat located @ 91 was replaced by Nimiq6. A few factors occurred with this upgrade.

Tighter footprint to the Canadian border and higher output power and alot (if not all soon) of xpndrs going to 21500/SR, Auto or 2/3 FEC, and T8PSK modulation.

As you may have read in other posts most people in the Mid to southern US have lost 91 all together now.

I did my first dish upgrade in NYC, NY.

I upgraded from a single LNB 18" dish pointed @ 91 to the 33" dish pictured below.

I'm only using two LNB's just for 82 and 91, out of curiosity I may try to load all four 82,91,110,and 119.

But I centered the dish on 91 for max signal gain.

It works fine with the new Nimiq6 sat from NYC, NY.

Hi Cmangle,

I merged your post in with the others in this thread, we are getting too many started on this subject, and they are getting spread all over the place.

It would be nice to keep them all in one spot.

Thanks for the update from your location.

Cmangle,
What is the max signal level you got for 91? I will try my 36"x39" dish with motor.

I agree 100%, I live in same general area with same results. Much sharper cut off.

hit 91 today(sunny day) with 36"x39" dish with motor. Signal level 67-80 all tps in NYC area. Almost the same level as 82, if you had 82 before you should have no problem with 91(new nimiq6)
