2.4 Channel Master Offset

Hello nelson what satellites are viewable with the dish at this location have you had a look at nilesat 201

Hi nelson_b,

You got a very good buy from eBay with that 2.4m CM dish and kit. The actuators are probably worth what you paid for the entire kit excluding your travel costs. I think you got it from the seller who also had the 3m Precision dish and the 4.5m dish for sale around the same time on eBay.

I am looking forward to your installation and it will be interesting to see what the 2.4m CM can achieve in terms of C, Ku and Ka bands and how they compare with the dishes of the small men. If I were to guess, I would say the Ka band might not be spectacularly greater than a high quality single piece slightly smaller dish but the C and Ku should really illustrate the power of a 2.4m big mans dish.

Hope the installation proceeds well and best of luck with it.

Rgds

Hi --
I can see 46 east o.k .... a few degrees further will be possible if i skew the towing caravan back a bit ....
west ? 30 - 40 not sure i need to fix the (short ) jack that i,m using to the other side to get that far ...
i can see 7 west ok without moving it .... can,t see anything from Nilesat 201 though ...
i can see 11595 V 22000 from E7WA , its listed as being on the NWA beam ... i,m sure it is looking at the signal db.... its a first for me i think..... the ME-NA beam is strong.

 

[Captain Jack]

Must be an north/south thing - it's coming in OK here on 1.8m.



Absolutely sod-all on 25.5e though. Not a blip. We really must be in a null here.

Indeed, it must be .... i checked when it came up for me on 2.4 ... not a flicker with 1.8 here ...

Signal levels pick up later in the day 36E will be of interest for me do you have LNB for testing here would appreciate any test, I get mena beam ok with 1.2 and a hint of nwa beam weather/ timing is /important

Interesting do you get any signal on the massive dish from 201 would like to see pictures of the big one

Hi - moonbase --

Yes i,m very pleased with my purchase .... it really was a last few seconds decision for me too,
i had been watching it all week and thought that i had talked/thought myself out of it .. l.o.l.

You remember well .. i saw the 3m Precision dish parked by the side of the house and the 4.5m dish in pieces in the garage , when i collected my dish from the seller.

I think you are probably right regarding K/A ... i borrowed a combined k/u k/a lnb from Evan last
week and had a brief look at 16 east and locked all the k/a transponders but one ... but not by much of a margin .... more k/a tests in the future no doubt ...

cheers ....

Nope, pretty much nothing. I get what can only be described as blips on one or two frequencies but it could be as much as just ground/sky noise.



@nelson_b - would be interesting to see 36E results on circular Russian transponders.

 

[nelson_b]

36E will be of interest for me do you have LNB for testing here would appreciate any test,

Hi -
Do you mean the circular transponders ? i, v locked a couple of them briefly in the past on 1.8 using a C120 l.n.b. and channel master feedhorn with original dielectric plate .... its in a thread on the forum somewhere ?

@nelson_b - would be interesting to see 36E results on circular Russian transponders.

will dig out the C.M feed and try later ... the skies are clearing a little here now .. conditions will need to be good i think even with this big dish ...and i recall there was interference issues as many Russian transponders were on the same frequency and s/r etc , as DSTV Africa but DSTV were linear ......

You've done well to get them with a small 1,8 circular package is what I would be interested in yes

I'd be interested as well. I just looked using the 1.5m PF. H are marginally stronger than V but it could be skew error. Most tps are ~1dB SNR although 25E is very close to some trees which give ~4dB ground noise at 28E. My calculations suggest a 4.7m dish for 11dB SNR. If the 3.8 wasn't in the shed in bits.......

Hi - Journey -
Clouds have broken here now so i just had a look ... i,m afraid its a long way under lock ..
i get 3.5 - 4.0 db .... listings on lyngSat say 6.6 needed to lock (and probably 1 db more i think at least , to get an unbroken picture) I will keep an eye on this one in perfect weather and in the evenings .... very unlikely though
regards ...

hi - s-band-
probably better chances in a south east location .... ,,
see my result in the post above ....

thank you nelson_b I always wanted to know what size dish would pull this in sweetly, looks like an even bigger one again, thanks for sharing this finding

Coming in OK with me with the 1.8 in Staffs

Hi -
@Captain Jack & @blademedia
Heavy showers here prevent me changing the l.n.b. + feed for 36E circular t.p.,s ..... so far tonight
I found the old postings - on here to refresh my memory about which transponders were strongest when a number of us were trying to lock these in the past ....

36B at 36.0°E (long thread)

and another ...
36E (Eutelsat 36B)

the situation regarding 12092 that "archived-1" first spotted - still exists (im getting occasional lock here with a normal l..n.b. set to H polarity) ... the only difference is that unless my memory is wrong ? it needs much higher db level to lock than it used to ... no chance with 1.8 anymore here .... Maybe you can C.J.?

 

[Captain Jack]

No chance down here. Some flicks of signal but could be a bird flying past. Or a pig.

There must be a side lobe up north for this beam.

I have a far better chance of locking 56e here...if I had line of sight.

Good going with normal lnb and conditions, should gain approx 3db with correct one thanks for taking time to look and links will have a read

The odd thing is i could never lock this one with the "circular" l.n.b. only the normal one? ... it was another two transponders that i managed to lock on the 1.8 with circular ..
