Dishes and Yagi Corner Reflectors

We need to move the existing Sky dish.  It belongs to Caroline in flat 2.


The dish shown by the red arrow is to be moved. It could go to the chimney shown by the blue arrow.  But the dormers may block the line of sight to the satellite.


There is another suitable chimney stack on the other side of the house, there are 4 shared owners of that stack!  There is also a brick party wall which projects about 50cm above the roof tiles.


The existing dish has 4 cables, 1 going over the roof to the front of the house, and 3 dropping down to the rear of the ground floor flat.


(The black cable which runs horizontally is the phone line for the 1st floor flat.)


The grey dish on the right hand chimney is old and will be removed.

Note that there is now scaffold across the whole of this wall, and the right hand side, and access is very easy.

The nearer of the two chimneys shown below will be removed.














There is an existing UHF yagi antenna in the loft. This is in the way of builders installing steel beams and joists and needs to be moved outside. It will probably go on the same site as the dish.


I also want a new FreeSat or Sky dish for use by two independent users once the loft is habitable (i.e. two different receivers supplying two TVs). 


The loft conversion will have two dormer windows projecting from the rear roof. Their forward edge will be ahead of the chimney. This could present problems with getting a line of sight to the satellite.




Is there enough space to mount 2 dishes and a UHF aerial on the same chimney?
If we mount the dishes on the suggested chimney, will they be blocked by the dormer windows that will extend out from the roof?  


If so, then maybe we can mount them on the party wall to the left of the dormer windows. (UHF aerial ahead of dishes, for best reception). This would be very inconspicuous.
