I'm not having you saying you are the only technician around here Halil!

Ok guys, I've just moved into my new home so everything is being done here for the first time by yours truly ...so here's the layout of my TV reception etc... (Picasso follows)



Everything works but the problem is that reception quality is poor and ever changing...

Thanking you in advance...

PS: Adjusting the variable resistors on the mixer does nothing.

Regards, GR.

G_R,
I am ready to come and see the system what we can do about it. Also i send u mail with Cc to İceman.
İt will be better to see it ,it will not make any sense to write on the forum.

G_R ,
Is it possible to get converter from RF to A/V in your place.
Your set top box must have A/V out put. Am i right ?
By looking your drawing job has been done in a amatore way. With booster you are amplifiying noise as well.Also every socket that you are not using it must be terminated with 75 ohm resistors otherwise empedance of the system changes.you can get reflection in the system its mean lost of the signal(weak) or ghost images on the screen.Rf power always changes due to propagations factors or changing power of the transmitters outputs that's way you get signal variations.

Before we do ,
i check the data of the first rf amp.
N-UHF1: 21-37 covers these bands.
N-UHF2: 38-69 covers these bands

u are using 2 antennas. one for analog transmissions and second one for digital transmission.
your problem start for a beginning with digital antenna in put.
as far as i know DVB_T transmissions at south are in channels 26,30,34,62 and 63 (i monitor them whşle ago with my spectrum analisor)
its means your signals for digital channals 26,30,34 will be week on the antenna 2 input.
for anolog signals channals from 38-69 will be weak signals.
my conclusion comes from below data link.

I just imagined u and G_R sitting next to each other and arguing that's why i lough.

we wouldn't be arguing....he's too scared of me.

And GR whats up with all that fagot equipment that you got? And then you expected it to work straight away

[Get Real!]

Firstly, great to see all the old regulars come together like before… what a crowd!

@Deniz

Thanks buddy… getting it all nice and ready for your summer holidays!

@Halil

Yes, there is a Scart connection for the Internet TV box but I want its signal distributed to all rooms thus the RF connection.

Great tip about using terminators on unused ports! It’s just a shame I’ll have to wait till Monday to buy those and try it out as I read your message late.

Btw, the techs who sold me the digital UHF said that it should work fine now and later when we move in that direction.

@Sotos

The Fagor mixer and booster came together in a box, and it was the only setup I could use given that I have so many points. Great tip about isolating the loss…

MyVision actually works fine with just a little bit of snow in there most likely coming from the rest of the gear.

Soto, tell me more… is Fagor considered junk equipment? It cost more that the other usual stuff lying around!

@Bananiot

Change house, change party… whatever next Bananiot? Change wife too? The beers are on me Bananiot, we can have them here anytime you all agree on my bar (hint-hint) or at a pub. Please arrange it.

@Pantheman

Good point… luckily it’s a star aerial network! But yes, I have head about those daisy-chain criminals! As I said to Sotos, the booster and amp came together to be used together so I’m assuming it’s ok.

@DT

Err, Ok… I whacked the TV right in the middle with a sledge hammer and besides a loud bang the lights have gone out… is that a good sign?

Thanks guys...

Regards GR.

For those interested, the poor reception problem has finally been solved by removing the amino (myVision TV box) from sitting right in between the mixer and the booster and routing it directly into the mixer via a spare UHF port where the mixer blends it with the UHF and VHF inputs.

The amino’s “in” socket is now unused as there is nothing to feed into it resulting in a setup that now shows all channels crystal clear including myVision.
