Installing Dishes In Spain for 2E Chit-Chat

[cat010]

Como siempre, todos los antenistas no son iguales por suerte, tengo un amigo que se dedica profesionalmente ("elMaestro" en foros), es instalador y el personalmente, aparte de avisar del cambio de satelites, el año pasado a sus futuros clientes, les recomendo esperar a que el Astra2E entrara en funcionamiento para ver los niveles de señal por la zona, sin saber nada, la recomendacion es 150cm minimo o mejor 180cm.
Si un cliente queria instalar una antena mas pequeña, se niega a instalar esta antena, quiere clientes contentos que llamen a sus amigos, no clientes cabreados en unos meses, si alguien duda de mis palabras, puede consultar al compañero Davidcmadrid, no instalo la antena de 120cm que pidio.
Por suerte, algunos medimos la antena bien y vemos su rendimiento, que no es igual para todas, soy un aficionado mas con equipos de medida.

As always, all aerial installers are not equal luckily I have a friend who is professionally engaged ("elMaestro" in forums), is installer and personally, apart from warning the change of satellite, last year your future customers, recommended them to wait to become operational the Astra2E to see the signal levels in the area, without knowing anything, the minimum recommendation is 150cm 180cm or better.
If a customer wanted to install a smaller antenna, refuses to install this antenna, want happy customers to call their friends, not customers pissed in a few months, if you doubt my words, you can consult the companion Davidcmadrid not I install the antenna 120cm who asked.
Fortunately, some good measure antenna and see their performance, which is not equal to all, I am an amateur but with measurement equipment.

Brian it was these brackets i was talking about the Spanish version of the t&k
did not realise it was so far back in the threads but a lot of holes to drill

well you might see me walking about dazed and confused in formentera for the rest of the week

OK I'll lookout for someone dazed and confused! Had to go to the Ayuntamiento today in Formentera for copy passports and Padron. Could have run you over then, if I had known

Didn't write the last message quite right, or did I?

Had to install a 1.4 Fam today ( I know it´s only a 1.3! ) on a four story town house in Quesada. Only problem was you have to go from the top level terrace, over the pitched roof, to a " well" to mount it! I know I don´t mind heights, but! Neighbour nearly phoned the ambulance just watching me, said I looked like a giant turtle crossing the roof with the 1.4 strapped to my back!
No health and safety hear!

OOOOhps! misspelt Here!

ie:- no change from 20 years ago....legally maybe but ¿¿¿ reality ???

OK, calling all LNB design experts! Or anyone who has had this problem before

Two adjacent houses sharing a 1.8 prime, three in one house, one in another. House with one feed had stupid electrician in who managed to take down the main trip while wiring a ceiling lamp. Power surge / interruption took down the feed to their house, the other three were still working ok, so replaced the lnb for a new quad. ( about 6 months ago )
Yesterday, the air-co unit tripped the mains again ( in the house with the one feed ) and yet again took out port 1 from the quad lnb. As port 3 is not currently in use have switched over to give service.

Have suggested they get a decent electrician in to check the earth bonding in both houses to see if either is without an earth connection. Cannot think of any other reason why a simple trip overload could blow the lnb.

All help appreciated, conjecture or fact!

If the electrician keeps taking out the LNB, TAKE OUT THE ELECTRICIAN!!!!!!!

Thanks, I would agree normally, but on this occation the electrician was not in the house when the air-co tripped the mains and killed port 1

But as I said, all comments welcome! Maybe should have specified the comments!

PS how is Oleg?

Are the two houses on different phases? Maybe some kind of cross-phase pulse is causing the problem?

Not sure, did cross my mind as well, but as I don´t carry mains voltage test equipment couldn´t check. Would be surprised if it was that as both houses are on the same plot, one belongs to " mum and dad " the other to " son and daughter in law ".
Not that means anything in Spain! ( Re electrical feeds, before someone gets smart! )

I would suspect a combinaiton of the air con cutting out and earthing problems - especially if one of the air con units is casuing problems. Why is it cutting out? That needs addressing firstr Then why does it blow the LNB? - my guess is a high voltage spike due to bad earthing on one or even both properties - and possibly made worse by different phases! Even if on the same phase, high earthing resistance between the properties could generate quite a high voltage difference when the air con trips as it would act a be a bit like a pulse casuing a high voltage spike. I have often measured upwards of 30v across neutral and earth within a badly earthed property and so differences across two properites due to a pulse could be much much higher.

Re the air-co, it blew up, apparently quite an old unit. Re the LNB blowing can only assume one or both houses have an earth problem causing spike on the neutral. As receivers have no earth connection can´t escape that way anyway, but am surprised it hasn´t blown the freesat box, or anything else in the house for that matter, unless it is because it is trying to earth at the 2nd house and all other electrical devices are obviously not connected to the 2nd house in any way.

Is the LNB properly earthed?

 

[joddle]

Hmm - It seems that a high voltage spike in one of the houses may have been the cause then - I have seen pretty high surges in Spain - sometimes up to 400v which actually happened in our own house a few years back when some idiot down the road cut through one of the of the phases in the street - blew everything in the house except the LNB!!!! But for you why only from one house??? Are the receivers different? - if so maybe one type has better voltage control and insulation properites than the other!!! or are the cables the same length in the houses - if much shorter on one house then maybe more prone to problems of voltage change

Don´t think I´ve ever seen an earthed LNB! Not sure how would effect the signals to the receiver?

In this case the dish is a big prime focus mounted on a concrete base on the roof of the 2nd house, so in answer to your question Joddle, the longest run is to the house with the single feed ( and the power problem )

Just had another thought, how would You earth an offset LNB, for example a BU single?
Cut the outer plastic casing and screw an earth wire to inner components?

Hmm that seems to stuff that theory then - but are the receivers the same type in each house? Why is one house more suseptable than the other? One good thing seems to be the isolation between the elements in the LNB - one was taken out but the other three all survived!!
