Wavefrontier again

syboit

Hi,

The recent high winds, claimed my wavefrontier dish. I didnt think the location I had it was much of a wind trap, but it had started to sway/wobble in the winds more and more, till finally the bolts came away from the wall and down it came!

So now I've repositioned it on the ground, at the back of the house. I haven't much room to play with though, I could only go back 4meters from the corner of the house (which is also just over 4meters high).
I found this formula on a sat website "Distance x TAN(Elevation) = Height" so with a 2.5m pole It should be enough to clear the house to reach the angle of the signals coming in.
So after that back story here's the issue, I've centered it on Hotbird 13", and I've found Astra 1 & 2 at the postitions on the rail I expected them. However 16" and 5W (at the other end did not come in). I haven't had much more time to play around with it, but could the skew still be off ?
I would have thought since 19" and 28" came in the rest might fall into place, but then again are these fairly strong signals and would probably come in anways?
I suppose the other issue could be pole not high enough to clear the obstruction.
Any thoughts, guidance, I've been over all the old threads on here even my original ones

Maybe, in fact quite likely, the dish is distorted after its fall.

Its unlikely to be a clearance issue as 16e and 5w are higher satellites in the sky than 19e and 28e .
If you can pick them up ,the dish should be able to see 16e and 5w.

28e and 19e are easy to receive as they are the strongest satellites and very close on the arc so even an incorrectly aligned T90 will pick them up.
Can you receive 13e ?

As Winston_1 mentioned ,is there any damage to the dish ,is it warped or dented ?

I ground mount my T90 ,its just too big a dish to mount on a wall in this country with the ferocious winds we get.
It really is asking for trouble mounting it up high on a wall .

Hi,

thanks for the replies, believe it or not no damage to the dish (though I will check again). Once the top "T" bracket gave way, the "K" backet started to buckle and bend (and with the amount of cables running to it), the dish almost glided down to the ground

Yes 13" is tuned in, on point 0 of the rail. I will try the other again over the weekend

i have mine on the side of my house. borrowed a scaffold set from my brother to get it high up so as to avoid a tree on the opposite side of the road.

when the wind got bad it used to vibrate a lot and there were signal dropouts.

now that it has calmed down things are back to normal.

it is installed on a gable wall with threaded rods going through to the attic with a metal plate on the back. i was more afraid of it pulling the wall down than anything else.

Here's what my Wavefrontier looks like. Its a 3 in 1 setup.

Thats what I was thinking of doing first day, but like that was afraid of the stress on the wall. I was starting to get that issue aswell where the dish would vibrate slightly and you'd get dropouts.

lucky when the dish came down it did no damage to the house or the dish itself.

I'm really amazed on how neat everything is

Now that the fine weather is back at least I can go fine tune mine again.
