You can modify the linear KU LNB (one meant for 121W) by taking off the 'white' plastic cover and insert a piece of plastic into the circular neck. Mine already has 4 slots such that the plastic piece can be inserted at +45 or -45 degrees. I can't remember what angle it was; but only one orientation would give me signal. The plastic I used is cut from an old bank card.
With a large Bev dish (24x26), signal strength ranges from 45 to 65 on the signal bar of a Dish 2700 receiver (120 full scale.) I couldn't get any signal from a 20" dish.
I used a regular LNB to aim for 119 first then replaced with the modified LNB. The Dish 2700 receiver is good for aiming because it will identify the satellite name. You may hvae to skew the antenna a bit to optimize signal strengths between various transponders. The modified LNB will only show signal strength for 118W satellite; no signal strength when switched to 119W. So you'll only get 118W channels with a Dish receiver. However, when used with a FTA receiver, you'll be able to scan it both 118W and 119W channels.

There now appear to be legacy-compatible FSS LNBs with an LO of 10.750 which do circular down to 11.70
examples: http://www.sindaltech.com/circularlnb.htm
Some folks are selling the twin on ebay.

Using the 121 FSS LNB from a super dish and converting it to circular as described above, is another way to get it done.
That would be dishPro compatible.

Default circular - 13th September 2007, 01:42 AM

Big Red is right it is easier to make a circular lnbf by add a plastic or fiber block to a linear lnbf than removing mat'l from a circular to make it linear. I've converted linear c-band lnbf's to circular for fta east birds. Not hard, forget about trying to move the lof unless you are a E.E. read read..... sorry about the grammer and spelling but it has been a high point beer night

I believe this is what you guys are talking about and looking for...........

LNB for 118.7w and 119w (To get them both from one lnb)


The name of it is Circular Dual LNB CB2008

It is for circular polarity satellites and it is a wide band LNB 11.7-12.75ghz, so can get 118w TPs as well as 119w TPs at the same time, if using a 30" dish, 118w is still a lower powered sat.

They cost about $25-$35

Could I get some more information on the conversion please? I know for 121W one you can uncouple LNBF assy from the front section by removing the 6 bolts in the middle then jamming a place of plastic in the square side(121W side) but what about other LNBF, such as starchoice ones?

No need of adding anything anywhere, just move the 121 LNBF to 119's position, and if you like, 119 to 121 by removing the 4 hex bolts. This works, because 119's wave guide is meant for circular polarities. I also tried turning the 121 LNBF 45 deg ccw but then I couldn't put all 4 bolts in place.

Is it possible to get 118.7 & 119 together on legacy receivers like the 2700 or 2800? My 2800 only shows 118.8 and not 119 afer doing Check Switch. However when I use any FTA receiver there is no problem getting both 118.7 and 119 satellites.

Has anyone successfully get both 118.7 and 119 working on legacy receivers using those new LNBs?

The LNB (118.8) is Linear not Circular Pol!

If you have a Supperdish 121 (twist the inner plate \===>/)

From another sit


Circular Dual LNB for both 119 and 118.8W
C$19.99
It's a brand new Ku Band Circular Dual output LNB with Dual polarization.

Ideal for all circular satellites, i.e. Echostar 3 (Dishnetwork 61.5), Echostar 6/8 (Dishnetwork 110), Echostar 7 (Dishnetwork 119), Anik-F3 (at 118.8W), Echostar 1/2 (Dishnetwork 148), All DirecTV, All Bell ExpressVu and other Circular Polarity satellites.

It's designed especially for catching 119 & 118.7 (Anik F3) at the same time using one such LNB. Each Output gives signal from both satellites.

Make sure you set LNB frequency as 10750, instead of regular 11250 in the receiver menu.

Make sure Anik-F3 (118.7) TP figure in your receiver menu is correct. Please visit this site www.lyngsat.com/anikf3.html for your information.


Features:
* Dual Output; Neck size: 40mm
* Input Frequency Range from 11.70Ghz ~ 12.75Ghz
* Output Frequency Range from 950Mhz ~ 2150Mhz
* ROC Brand; L.O. figure: 10.75Ghz;
* Extremely Low Noise Figure: 0.3dB
* Low Phase Noise for Analog or Digital reception
* Brand new CB2008A type with Excellent stability
* Best solution for individual and multi-satellite systems
* Weather-proof O-Ring and Gasket inside.
It's ideal for Dish 500 and Dish 1000; and check the pictures below for installing it on a Superdish121.

--------------

Hardware Need:

Circular/Linear Polarization LNB for 118.7/119. This LNB allows to receive the 118.7 & 119 signals at the same time. It's a special circular lnb that has a low frequency of 10750. Use this with a 33" dish, to receive both signals 118.7/119..

SPECS:
Polarization: Circular
Input Frequency: 11.70 - 12.75 GHz
LO Frequency: 10.750 GHz
Noise: 0.3 dB (Max.)

Before you doing these, you should have all the hardware already installed.

Antenna Config setting:

Satellite: 119 or 118(121)
LNB Type: Standard
LNB Freq: 10750



Add 118W Transponders infor into 119W

Before adding 118W TP infor, delete all the channels from 119W, These will avoid double channels when performance Channel Scan.

I hope that clear every Q

I'm sure Justin would sell you / them some ad space if you / they want to advertise.

EL_Pirata, the LNBs on the dish500+, dish1000+ and dish1000.2 are all circular polarization. (And my supperdishes are all in the Kenmore )
