Hello Friends,
Thanks for the replies and appreciate all the information and suggestions.

So just to update you. The job is restricted. There are trees and buildings blocking signal reception from
all satellites looking right to left 60W to 16E (Includes 1W, 13E, etc). There is a small possibility of a signal
from 19.2E.

The unobstructed sightline is from right to left 23.5E to 55.0E. A motor would have been the optimal solution.
They don't want one, so we "gives the peoples what they want" so to speak.

There could definitely be trouble brewing with reliability and disecq switches, etc, but hopefully if we get the
install right the callouts should be minimal if at all.

Would love to get them the Africa signals/beams, but we are unlikely to install anything larger than a 1.25 gibbo.
I discussed the larger dish options, cost and complexity. I also explained that the larger dishes need to be securely
attached and installed to withstand extreme wind. The larger the dish the larger the "sail".

One of the complexities of this job is that they want it installed in their garden with no structure to attach T & K
brackets etc. I am currently consulting with an engineer on what to erect in the garden that will house the dish.
We can't simply put a few bricks, concrete and small pole in the ground at a low level as the neighbours fence
is well over 6ft+ high including gravel boards.

We told them that we need to get the dish at least 4m+ high above ground to get the signal reception needed.
Hence, we are now racking our brains about the cheapest structurally sound and secure construction option that
could house a dish, and can be done under permitted development, thus not requiring planning permission.

Also, before you suggest it, there is no building that they can mount the dish on. It's a unique job.
Not a dig at you @kippysat my friend, but you might want to get a reputable satellite installation firm involved they will know what to do.
How close is the fence to the possible dish installation ?

Not at all mate. That is fair and why we are talking to the engineer. The customer has come to us because of a recommendation.

I know they spoke to a London based firm and the quote was ridiculous, so they are trying to do this on a budget.

Just get them a quality iptv unless they are using it for gambling, be easier lol

might be better to wait 'till next week before doing that as i read there will be "knocks" on doors this week regarding IPTV :eek:

A 6ft high fence is not a big issue for blocking line of sight to the satellites required at the install site.
I dont see why you need the dish to be 4m high if you have unobstructed line of sight between 23.5E and 55.0E apart form a 6ft fence

You can use Dishpointer to work out the best location on sight for your install.

As there is no possibility to secure bracketry to a building then my suggestion would be to consider the following 2 options.

1. Secure a tripod ground stand or NPRM to concrete kerb stones (cheap from local builders)
2. Dig a hole and use an appropriate diameter pole embedded in concrete in the hole.

If you have doubts that concrete kerb stones will not provide anchorage I have a motorised 1.5m dish on a tripod ground stand secured to three concrete kerb stones
The setup is rock solid, never needed adjustment in years apart from when the patio was relaid. The kerb stones I use are 3ft x 6" x 5" each.

This install has all the ingredients for a disaster so make sure you have a reliable and skilled installer.
There are plenty of puffers and blaggers out there who talk good shít but are clueless.

Thank you Moonbase. OK, so I can expand on the site restrictions.

1. The height of the fence to clear it is actually over 7ft+ as the neighbours sit on higher ground.

2. The back of the neighbours house has a sloping roof that is currently just over 4m at it's lowest point.
The roof line is at an angle that is hard to describe, but the slope is such that your sight line to all
satellites west of 19.2E is obscured from the ground level looking up. Look east of 19.2E and you can
see 23.5E, 28.2E, etc up to and including 55E.
The neighbour kindly allowed us to measure the height of his roof's lowest point once we explained
what we were doing and why we were there.

3. The neighbour also have four cypress trees along the fence and they have been trimmed, but are
currently about 3.5m high.

So you can see that even if we dug a 500mm/600mm hole and placed a 4m pole in it, the above ground length
would not be enough to clear the trees, especially if we place the pole within a metre of the fence and
trees. That length of pole might work if we are more than 5m+ away from the fence. Just using rudimentary
geometry, the further away we are from the neighbouring fence the lower the height of the pole required
to view the satellites.

My concern is that a single pole in the ground, embedded in concrete, will not be sturdy enough nor
resistant to wind gusts once a dish acting a sail is added. Maybe your tripod idea would work, but
how high would the tripod section need to be to provide the strength required?

I had a thought that a three pole setup in the form of a tripod, linking the three poles so that the
structure would look like the tripod communication towers we see across our country might work.
However, I am not an engineer and could not guarantee the structural integrity and wind load capacity
of such as design.

Now you can see what we are racking our brains about solving.

Have you had a satellite installer round to do a site survey?
Your immediate need is to get the site surveyed and get feedback from an experienced installer who has experience with a multi-lnb setup on a single dish.

Until you have had the install site surveyed eveything is just conjecture.

What is the location of the install site, members on here may know of a reputable local installer?

Someone with experience of installations and multi-lnb set ups has already been on site.
