The receiver doesn't necessarily operate at 4.5 to 4.8 or 3.7 to 4.2 or 10 to 12 gigs , it receives an I.F. frequency band output from the LNBF and depending on the model its usually 950 to 1450 or up to 950 to 2000 mhz

Check the spec on the LNBF ,it will give you the input and output
some will work a little below and above the spec but it depends on the manufacturer
If you have several receivers look for the Sat lnbf input with the largest bandwidth so if you have 950 to 2000 that would give you about a 1000 MHz so if the lnbf starts at 3.7 theoretically you might make it to 4.7

Hope this helps a little

Yes, very helpful, thank you. I will buy upper c band LNB and test, I think v7 box has preset LNB configuration for L.O. of upper c band LNB?

V7 has several settings for the LO ,usually in North America 5150 is used ,you can change this but it will just change the frequency that is displayed .

Freesat V7 is Input Frequency Range 950MHZ-2150MHZ

So choose a lnbf input for the desired range on C band and make sure the output falls into the input range for the V7 (950 t0 2150 as noted on the official website )

the fact is the band of frequencies the lnbf puts out to the receiver will be received if the receiver has the same input bandwidth ,you can even program in a range for the LO in the ku band into the V7 and blind scan in a c band lnbf ,it will work but all the tp freqs will be wrong and any preset sat list will not work correctly .

The main thing is to get a LNBF that the input matches the frequency you want to receive and make sure the output matches your sat input freq range on your receiver

Just looked
several 4.5 to 4.8 lnbf units on ebay , they aint cheap

Just for example off ebay ,not sure if it meets you own exact requirements

Norsat 5250I Specifications
Input Frequency 4.5 to 4.8 GHz
L.O. frequency 5.95 GHz
Output frequency 1150 to 1450 MHz

The output falls into the range of the receivers input 950 to 2150 and the V7 will accept the LO freq of 5950 ,i checked my V7

Nothing shown on lingsat for North America on these freqs
What do you what to watch?
just curious if you can say

Good luck

That is Ka band not C band circular

I have used that LNBF for years and it has nothing to do with Ka band? There are four ports 2-Circular and 2-Linear. which you can split with s Diseqc switch at the dish.

LNBF C BAND

Postby ftauser » Tue Jan 15, 2019 8:23 pm

I have a California Amplifier C Band dual polarity LNBF that came with my previously owned dish. Don't have any idea how old it is. I'm on a 7' mesh dish and live in south Arkansas. I have a hard time with a few transponders and wonder if a new Titanium C1 PLL LNBF might be better than what I have. I've looked at the California website and it seems their LNBs may be top of the line by looking at their prices. I've also noticed almost everyone on this site and other FTA forums use the Titanium C1 PLL. I figure there must be a reason for that.

Yes there is a reason we use them, they are the best for the money, just watch out for clones.

When I decide to get a new LNBF it will come from Titanium Satellite.

To make sure you do not get a clone buy direct from Titanium,they have a online store, and are the same price as Ebay the owner is Bryan and he is located in California.

Some of the East Coast NA/SA Satellites like 34.5 west and 20 west that have PowerVu channels have Cband Circular (Right and Left) signals and so you need a CBand Circular LNB for some East Coast Satellites but the middle to West NA Sats all have linear (Vert - Horiz) signals.

Beers to all ! :D
