Ku band, can that be used as a normal lnb, for astra etc,


It can but it doesn't cover the full Ku-band range (10.7-12.7GHz), so you will be missing a significant number of channels.

jpsr said:

but its just the top part thats bolted to the bigger lnb that says ku band, could the bigger bottom part be ka band for receiving.


That's most likely the transmit part and useless for Saorsat.

Ok thanks for the info,
Do the lnb's for soarsat come with a 23mm neck, the lnb holder on the channel master is for a 23 mm lnb.

yes and a 40mm collar adaptor.

onwave look good value

The neck of the LNB's are 23mm. Onwave seems to be the cheapest place to buy them.

Agreed. Diseqc and especially Multiswitch always put 28E as LNB1

I'd take the Welsh or Cornish coverage with a Lump of slate or tin.
still booming in here in the slates with a dish that's very tinny this is after the reported signal drop my signal has increased but this is due to using a proper lnbf

As a blow-in oggy eating tin miner, I'm doing ok at the moment. Signal Quality varies fron 45-58% on a cheap Ross 650mm ish dish, using the new inverto LNB, and I have yet to spen hours on my roof tweaking and peaking the dish.

too cold to spend hours on the roof the only problem that may arise is the other spot beams of the same frequency as been reported here but time will tell

Inverto have the specs for the LNB on their site now:

http://www.inverto.tv/products/product.php?id=241

This pioneering WHITE Ka LNB line was designed to enable reception of the new high bandwidth satellite TV, radio and data services in Ka band that are being launched across Europe. This Twin Ka Circular dual polarity LNB was specifically engineered to meet the reception requirements of Eutelsat for its KA-SAT satellite located on 9° East (e.g. Saorsat – Reception of free Irish TV by Satellite).

The LNB features two IF outputs and supports connection to two different satellite receivers. The LNB was designed to be used with standard offset antennas of 60-90cm diameter and F/D or 0.6. The feed of this Twin LNB is designed to fit as close as 4 degrees to a allow reception from another satellite over the same dish in Europe (for example - universal Ku LNB receiving the popular Hotbird 13° East). The external diameter of the feed is about 23mm and it is supplied with 40mm ring adapter to ensure compatibility with standard dish antennas. This LNB is using the highest quality components to ensure outstanding and consistent performance and durability and is manufactured under rigorous test conditions and strict quality standards.

main features:

•Pioneering LNBF for reception of satellite services over Ka band
•High Frequency and Gain stability
•Low Phase Noise
•Low Noise Figure
•Low power consumption
•High Cross-Pole performance

KA-SAT downlink coverage
(See map on site, does not show any spots nor coverage)

KA-SAT is the first High Throughput Satellite (HTS) in Europe and marks a new generation of multi-spotbeam high-capacity satellites. It is positioned at 9° East and covers Europe and the Mediterranean basin and has 82 tight Ka-band spot beams across Europe. Source: Eutelsat

To learn more on Eutelsat KA-SAT satellite – visit: http://www.eutelsat.com/satellites/9e_ka-sat.html

The LNB is suitable for the reception of Saorsat - Reception of Free Irish TV and Radio by Satellite. The Saorsat service is available via Ka-Sat @ 9E, using Ka-Band (Left Circular Polarised for Ka-Band on 20.185GHz).

Just to let you know, I got Saorsat working just on the outskirts of Belfast using the Onwave LNB and dish kit. It's really easy to setup and align the dish with one of Maplin's cheapo satellite meters, and the STB locked no bother at all. Remained stable through the snow last night too.
