Nilesat: Narrower Band LNB's and Gain.

Turok,
As you know, I have a DRO WDL 1000E from SMW that functions well, but it is the cylindrical type, NF 0.8db TYP 1.0db MAX. It weighs 256g. It is a WR75 like yours.
I keep it for comparison purposes. It is a V/H switcher and usually I use the high output of it.
 
I've got the same lnb WDL type E F-connectors @ High stability LO. +/-1.5Mhz Part Number 122520 which i have not had the time to fit and test on my dish, due to time and work load :( but will do in couple of weeks hopefully. (Roman David if you reading this my friend, i have not forgotten your request for photo's i will get these to you asap :) )

I also purchased the X-line type E lnb, which i passed onto a friend who is testing it for me on his dish. He seems to have a small problem which is beyond my scope i hope one of you kind gents can help.

when using X-line type E lnb with my nokia 9600s with dvb2000 switching between low to high band is working fine like a normal universial lnb functions but he tryed using on a nokia dbox2 with MD-Image v5.31 and can not seem to get the bands to switch.

He has the following information in the zapit.conf

diseqcType=0
lastChannelRadio=23
lastChannelTV=4397
lastSatellitePosition=192
lnb0_OffsetLow=9750000
lnb0_OffsetHigh=10600000

P.S Turok i will get in touch with u, regarding the poloriser, sorry my friend i just been very busy at work and have no time at the moment. I wish i had more time to play with this brillant kit i purchased but hey ho that's life

Regards

BoSS
 
okay okay no problem,then you want polariser ,contact me this month,otherwise,iam on holiday in middle of december!

testing norsat and smw together i must day,that smw is better,in 10-11 ghz range,and not soo "good" on 12 ghz,and on norsat it is via versa !

but smw when stop produciton i think,sooner or later will imposible to get,because,they are all selected handmade.)
 
Somehow, this thread has veered off course.

The SMWs referred to here are switchers "Universal or quasi so". Does anybody have experience with the single band SMW LNB covering the 11.7 to 12.75 Mhz (DRO-10.75-F).

A comparison with the Norsat DRO 4206A would be most useful.
SMW's DROs are not high stability, because their best version is 1mhz.
The Norsat 4206A claims 200khz the 4106a claims 100khz.
High stability DROs are useful for small signal rates transponders and Feeds.

There is no use talking about the PLLs because they should be compared to PLLs of other manufacturers and especially that they are not destined to the consumer TV market.

Any comments on this is welcome.
 
okay,yes there many lnbs on the market,the we should test,but they are mostly not easy to get!

on the dxcat site,they taking about semi profestional japanese lnbs,that coasts 900€ each,i have old japanese lnb here,from old analog days,where V/ and H were seperatly installed,its called gigasat made in japana,anyone can some say about this brand?
 
Typical S/N ratio for that transistor is in range of 0.5-0.7 dB :)

Yeah, I would like to know myself, as well. Can you buy them new? Do they still make them? Probably, not anymore?:confused:

I think there must be manufacturers who could custom make you an LNB. Maybe, Seavey Engineering?:)
 
dont think so,it looks like that they are out of production long time ago!
contact the man from the dx cat website,maybe he can help you!
but 900€ for one lnb,sounds real high price:)
 
Precision Gold NF 0.5db is selected from NJR6921 just as are Norsat 7000/6600.
Because of the simplified requirement as to DRO stability (1mhz) and the absence of a filter (necessary in VSAT). The Precision Gold NF 0.5db series is cheaper for TV use and promises better SNR.
May be a good contender for the 4000 series from Norsat in simple applications.
