Bad practice & Nightmare installations

[jeallen01]

Heard of an "inverto" LNB, but never a "reverso" one

(had to take a very close 2nd look to see what was "wrong"!)

Maybe it's a disguised surveillance camera?

The zone 1 could be the primary reflector in a Gegorian install.

I noticed this on the side of a house I passed one day a couple of weeks ago and it amused me...

lol, seen that before.

The zone 1 could be the primary reflector in a Gegorian install.

Meaning that the secondary reflector ought to be "very small"!

 

[PaulR]

That's absolutely right. So small it doesn't show up in the photograph!

 

[Channel Hopper]

A secondary reflector can be of any size, and distance from the primary, as lomng as it doesnt interfere with the incoming signal

Spotted this satellite & terrestrial setup at a community centre this evening...



...for context, the top UHF aerial (vertically polarised) is aimed at Clermont Carn in the Republic of Ireland, while the lower two UHF aerials (horizontally polarised) are aimed at Divis in N. Ireland. I'm not sure how exactly they were all set up, but it certainly seems that all three UHF aerials weren't installed in one go, even though both aerials aimed at Divis have suffered some element damage (weather or otherwise). The main problem I see is that the lower Divis aerial (manufactured by either Televes or a knock-off of their design) has its boom going across the face of the satellite dish. It's unlikely that it'll severely affect satellite reception, presuming the dish is aimed at 28E, but it's hardly good practice IMO.

Edit: Bonus points for pointing out that the top two UHF aerials are far too close together for them not to interfere with each other, but this is not a rare practice in Northern Ireland.

 

[Channel Hopper]

Aerial 2 (going down the pole) looks like it has been semi-converted to dual polarity.

 

[Captain Jack]

Plenty of installations here with UHF aerials sitting over the top or across the Sky dish...

 

[jeallen01]

Near here, there's a low-rise block of flats with steel-framed balconies and with the open framework covering about half of each balcony to the full height of the flat - and one of them has a Zone 1 dish right behind, and against, the framework with only half the dish face having a "clear view" of (I presume) Astra 2! Must "work" as it's been like that for several years!

 

[Captain Jack]

Or it's not connected at all!

 

[jeallen01]

Or it's not connected at all!

Possible but somewhat unlikely because the block of flats is fairly recent (around 8 yrs), and thus also the dish installation - thus I assume that the dish is working, or at least was working after it was installed!

Thoughts?

Cloudy!

Thoughts?

an internal aerial would have probably sufficed.

Thankfully not Antiference. Televes ?

It's clamped to nothing that will keep the aerial on station unless the rest is glued down.

Does it float your boat ?

 

[jeallen01]

an internal aerial would have probably sufficed.

Possibly not - because that prefab building is probably metal and that would make it a pretty good Faraday cage, which will screen out most of the signal!

 

[PaulR]

Just havin' a rest man. Nothing to see here. Move on.

The worst thing is this was seen very close to a train station platform....... I feel some kind of court case coming on accompanied by strong winds.
