Dual C&Ku bands LNBFs with Diseqc

Zaphod

For the select few who might be interested in dipping their toes in C-band, and who don't want to go to the trouble or expense of a corotor, these dual C/Ku LNBFs with built-in Diseqc switches are worth a look. Retailing for about US$50 and can be operated with any receiver, even a Lidl SL65-12!

Good Stuff, whenever I get back to the fairland of ireland im planning on maybe dabbling in C-band just for a look like

Hmmmmm. Be nice on the 1.7m mesh dish for Cband...

I feel a purchase ..

I can't see purchase address though.

What C Band can you see here? I'd guess Badr C (ex-Arabsat) for one.

Not 100% of cheap ****e FTA boxes support C-band but both recent Lidl offers do, so you're right there.

Depends on the dish, but Arabsat 26E and PAS9 58W have high output over Ireland and should be possible even with small dishes (~1M or maybe less).

Unlike analog, there's really no difference between digital C-band and Ku-band so all you need is a receiver that allows you to change the LO settings for the LNB/F. All the ones I've seen have this feature. Even a POS that doesn't, such as a digibox, could be used for C-band if you do the sums e.g. 3722MHz equiv. to 11028MHz (IF = 1428MHz).

What I was getting at was that only the higher end receivers support corotors with polarizer control outputs (+5V, Pulse, GND) and voltage switching of bands with 'Wideband' Ku LNBs. By contrast, the LNBFs above use simple 13/18V switching for polarity and 22KHz tone switching of the Ku bands - just like your standard universal LNBF.

Thanks. I was going to use an old Drake to control the LNBF and feed the IF to digital receiver. But this might be better.
