Thread: Chapparal co-rotor dual c/ku vs. BSC621-2 Universal C/KU BAND SATELLITE FEED HORN LNBF

I was wonder if anyone out there has had experience with both a HTS Twin Tracker Feed Horn Made by CHAPARRAL(what i refer to as a plain co-rotor ). and a BSC621-2 Universal C/KU BAND SATELLITE FEED HORN LNBF?

I wanted to know which one returns a stronger signal?

I currently have a c/ku band co rotor circular/linear feed (international) with a mesh (6 ft) dish. I have dual lines one for the ku and another for c band. I am using a 4dtv as a master with a pansat 9200 as a slave. I have splitters and a disecq switch inside to have it all come together for reception of both c and ku on both receivers,

I originally had a plain co-rotor with ku/c band and i recently replaced with a co rotor dual c/ku (international) linear/circular feed horn. I noticed some small signal loss when going the the linear/circular and i am thinking of going back (to the plain co rotor), but wanted to know if the BSC621-2 Universal C/KU BAND SATELLITE FEED HORN LNBF is any better. I am guessing not, because its sending both signals down one coaxial line, but I could be wrong about that.

Basically, i need everthing i can get and I wanted to know what would be the best feed horn with minimal signal loss. I appear to have problems with 8psk signals.

Thank you to everyone and all.

Not exactly what you asked, but this is a very good comparison. He did a very thorough job. Many here have had good success with the BSC621-2.

I appear to have problems with 8psk signals.

Bigger dish would fix that. But careful tweaking on the 6 ft may be beneficial.

co rotor dual c/ku (international) linear/circular feed horn

Remove the dielectric plate for linear polarized(domestic) satellites. Will introduce some loss if left in place.

The most effective use of your money would be a bigger dish. But if you want to drop a "Big Block Motor" in that Chevy Vega. Score a BullsEye 2 Dual Ortho Feed Horn & 4 LNBs.

Thanks Fat air. Thats my problem. 2 questions though.

1. How do i remove the plate
2. wont that prevent me from recieving domestic (US - canada) signals ? I would rather recieve those than the circular (non domestic ones) or do i misunderstand you?

I have a BullsEye 2 Dual Ortho Feed Horn & 4 LNBs., Perhaps i will swap it out on that dish. But, I really wanted some insight into the others.. Thanks for the info./comments. Its all good...

Thanks for the link. I will take a look. I appreciate it.

1) remove the cover from the open end of the feed throat. Slide the dielectric plate out. Replace cover. 2) no, the dielectric plate is only required for circular polarized signals.
There's pictures of the dielectric plate inserted in the BSC 621 here

If it's inserted, there's quite a bit of loss on linear signals.

Thanks FAT AIR, but there is a problem. It seems that your response (and the diagram) were relating to a BSC 621. I currently do not own one of those. I was considering it, but you made me think. My current chapparral feed horn contains a dielectric plate (a chapparal co-rotor II +), but i dont know how to remove it. It will not just slide out, there is something like a butterfly nut (but not) on the end of the plate. I believe the whole plate rotates for sqew, I could be wrong about that). If it doesnt move then that nut on the end is there for something. Are you famailiar with the chapparal co-rotor c/ku with a dielectric plate? If so, is it possible to remove the place without damaging it . if so how?

Does ANYONE else have experience with the chapparal co-rotor II+ c/ku dual feed horn?

Thanks again
