Newsnet on Ka Band A

[mapperuo]

I picked up a cheapy Chinese KA Band lnb the other day and have been messing with it, I am able to get the Newsfeed channel but Im noticing the H/V scans are identical which implies some sort of config issue? Anyone maybe able to point out anything that may be wrong with my setup please?

EBS reports similar, deffo something stupid Im missing

It will only be a single polarity LNB, that's to say you would have to physically turn the LNB itself in its holder to get true horizontal. The LNB will not accept voltage polarity switching. If you have it set for it up for vertical, just scan vertical polarity rather the both.

Gotcha that makes sense, Ill try peak for vertical then as looks like the ITN stuff is all in that.

Welcome to Ka land, show us what lnb you have bought just to satisfy our curiousity and what dish are you using it on.
Not the best day/weather for Ka sigs for us - checked out Newsnet earlier and also Band D Ka 16 & 7 East and signals down quite a lot
** Quite good signal level you have got there as well for your location .

My original plan was to stick it on my 1.5m Gibby dish but the signal for Newsnet was 7db so pretty crap, I maybe need to try again and do some LNB adjusting.

Right now its on a 1.8m Raven, the dishes are 100 meters away from my house so I've sadly had to dig out the old coax lines I ran years ago as I've since converted it all to fibre.

It's some standard coax to a joint in a cabinet then WF125 to another cabinet at the house and more standard coax inside, so I know for sure it'll be 1-2db loss on that.

Still, considering its raining today some fiddling has got 12.3db not too bad!

Ill wait until some actual OBs pop up, but this chinese LNB seems ok for a cheap way to get your foot in the door for KA Band.

EDIT: Just realised the above scan is H... Doing V gets 12.8db, must remember and stick to that!

Excellent ... is that one of those lnb's complete with cone feed i posted a link to the other week or so for about £160 'ish.
Don't forget to bung a bit of credit card plastic or similar in the feed throat to get circular pol, [might need a bit of experimentation re: size] and point up th 42East for the Turksat Ka channels

Aye it is! £170 including postage, didn't have any import tax, Took a month to get here, though in the sellers defence half of that time as just sat at Heathrow doing nothing, thanks Royal Mail

And thanks for the suggestion will give that a go once I see what else is out there.

The seller I got it from on Aliexpress had a free returns policy too so was a bit of a no brainer to atleast try it.

I think it's pretty good value especially when you get the cone feed as well , granted it's not as cheap as your Ku Universal lnb £6 ebay buy, but ready made 'Off the Shelf' Ka equipment has never been cheap- the feed is getting a bit rare to obtain on it's own now days, they could be picked up for around £35 ish a couple of years ago but not any more.
Just checked Newsnet again on the analyser and it would seem they have turned the wick up for sure due to the weather conditions.
* meant to say also re: tweeking - Ka is more of a bitch than Ku or Cband to find the absolute best performance on any dish, it boils down to millimeter adjustments to hit the money shot

Yeh 160 is about the same as I paid for each fibre KU LNB, it's an expensive hobby!

I wonder if power washing my dish will have any effect, I noticed in the photo is absolutely filthy... Neglect for ya

Don't forget to bung a bit of credit card plastic or similar in the feed throat to get circular pol

If it's a contactless card, avoid the edges of the card where the tracks for the NFC loop are embedded

Could someone see what the ITN Newsnet db level is today? I am getting a massive 3db.. whoops.

I'll have a look at it - will only be on my 1.2 Gibby though in North Notts.
I'll be back

Promax specky reports it at up to 12.5dB max, CS very similar. Slightly overcast down here 17k north of Nottingham.
Ka's a very touchy animal, does'nt take much ie: weather or slight mis alignment to upset the results.

Cheers! I shall investigate then this end then.

Here I received the same LNB from China, tuned a 1m antenna to Astra 19.2. But I had to suffer a little, it didn’t work right away, first I put the LNB as you didn’t have a signal, then turned it like in the photo and the signal appeared.
The signal is not very good, but the weather is cold and warmer, I'll try to adjust it.

Not much in the way of feeds from ITN these days, but Newsnet is nice and strong..

 

[Llew]

Still strong enough for me to skew my Hughes LNB to include EQUTV on H Pol.
