multi satellite dish options

wil

I am considering replacing my multi satellite dish farm with a single dish option for foreign satellite (will retain Sky dedicated mini-dish)
The Wave Frontier T90 I have seen mentioned elsewhere looks like it might suit my requirements.
Does any one have any much experience with these and do you see them as a viable alternative to a motorised 80cm dish?

My own initial thoughts are
No motor to allign and maintain.
Fast satellite switching and no noise
Comes with 6 lnb holders for 200euro locally so comparable or less than a motorised option - I have several lnbs which may be suitable so that keeps the final cost down.
Against are -
Dish weight
extra cabling and diseqcs
Would need to be kept out of sight, not only for usual reasons but because of its unusual look could be a burglar magnet.
I think I should mount it on a short 60mm dia pole concreted in at ground level for both stability, wind, ease of access and allignment.
Would need to put a protective surround/cage for the inevitable football, cat, toddler interference.
Your thoughts or experience greatly appreciated

Regular 90cm dish ~ 15 degree spread, limit 3 or 4 satellites
Wavefrontier T90 ~ 40 degree spread, limit 8 satellites for one receiver
Motorised dish ~ 120 degree spread, limit in Ireland about 22 Satellites on a 1.1m dish

The T90 is less wind load than my 110cm motorised.

EMP-Centauri has a multi-LNB switch for 8 LNBs that simulates GOTOx because a regular Diseqc receiver only works a 4 ways switch

Have used a T90 for almost 3 years now with no problems. Currently have 4 lnbs on it but did run it at one stage with 5. It currently feeds 3 separate STBs (so motorized system not an option). Its mounted on the back of the house and it has not moved even with all the wind we have had. I occasionally check all the bolts etc., but nothing has gone wrong.

I got a T90 from this crowd last year. I had a Triax 110 on a polar mount before hand and the T90 is a lot sturdier. One problem with them is they need to be mounted on top of a 60mm pole and these aren't standard here.

I also have the emp 8 way diseqc switch. It's very quick changing between the lnbs, but there is some signal loss from it.

Thanks. Website says can take 16, shop says 12, watty says 8.
I guess 8 is a more realistic manageable number
Is there fade towards the edges or is signal evenly spread across the dish?
I have one major problem developing, a very large neighbours tree rapidly encroaching on my satellite sky, the advantage of my dish farm is I can position them either side for different sats, I am wondering if this developing situation could render a single position dish very difficult to locate.
I have my doubts about them being amenable to topping it for my viewing purposes.

You can potentially have more than 8, but not easily or simply connected to one reciever.


Pick middle satellite of your range. Put on LNB on middle of bar. Add other LNBs (for weight) either side correct number . Align dish.

Then align the other the LNBs withouot moving dish.


My motorised 1.1m Triax and Motek motor and 90cm 4 x satellite Disitribution system (quattro LNBs), 28E, 23.5E, 19E, 13E. The C-band LNBF is a Dual and connected to the Distribution System



The middle is motorised and the right side dish can be extended to feed 1000 receivers with 4 satellites. It feeds 7 satellite receivers, one is a dual Tuner PVR.

One of the quattros is off it and lying on wall. Obviously the 2nd LNB from left (between Sky & Astra19) is not a Quattro

The left dish is due to be replaced with a 1.7m mesh one.


Here is my original setup:

13E and 19E both analogue receivers then. This was about the time I changed from Sky Analogue to Sky Digital

You are like SETI ,Watty ,that is some setup you have.;)

Ulsterman 1690

Another advantage of single dish multi LNB setups is that with dual LNB's and a second Diseq switch two recievers can be used

Or four recievers with quad LNB's and four diseq switches.

Id be interested myself in a dish that could do 13/19/28. I know that it is possible to buy multi LNB holders/brackets that fit onto an existing dish but the ones Ive seen so far are fiddly to set up and look a bit flimsy

can you tell me who made that dish. i cannot see from the web site.
not sure if there is a difference between the various manufacturers.
planning to replace a minidish with a t90. (my 1.1 channel master motor gave up the ghost).

This is where I bought mine a couple of years ago.

They're made by Wave Frontier, USA.

thanks.

there seem to be a few manufacturers and wave frontier claim to the be "original". just wanted to make sure as the web site did not specifically state who made theirs.

What are you receiving with the cband lnb-f

lads need some advice on purchasing a 1m motorized system cause it gets fairly vindy where i am based ..
has any ever used a 1m mesh dish and how do they perform as they wont catch as much vind and if this is not a good option should i go for an aluminum dish ..lighter and less motor stress

watty

Mesh for Ku band has as high or higher wind load. Mesh is just for cheaper manufacturing and shipping cost.

Only at 2Ghz and below does mesh start to have lower wind load.

Some larger mesh dishes are not for Ku (mesh too open) but for C band (3.7Ghz to 4.2GHz)

Lightweight Triax 110cm is biggest in a sheltered place for Diseqc motor. If you are in exposed / windy location and want 90cm+ you need a 36V motor system, wich can be driven by a Motek Diseqc to 36V motor adaptor. I'd go for a 1.2m or 1.4m then.

You need 4" pole and lots of concrete.

achiman

watty,
thanks for that advice its all a learning process at the monent and any advice is greatly appreciated ..
