Invacom LNBF for prime focus dish?

[MikeC55]

I currently have a Pansat 3 foot portable satellte dish (prime focus) and an old .6db Pansat LNBF. I am thinking about purchasing the Invacom SNH-031 (LNBF .3db) and installing it on my dish.

It this possible? Can the Invacom SNH-031 be installed on a "prime focus" type dish?

I read Cascade's review but not not see if this LNBF could be used on a "prime focus" dish.

Thanks,

Mike

You'd have to first make sure you can mount a C-120 flanged LNB on the Pansat feedhorn. I'm not sure what they use as an interface.

I pulled a 36" prime focus dish out of the trash a couple of months ago. I haven't set it up since I'm sure my 30" offset Winegard outperforms it. The LNB blockage on a prime focus of that size makes a considerable difference.

The dish I rescued has a screw-together assembly which locks the feedhorn to the feed support arms. The LNB is secured to that assembly with four Phillips screws. It is (I believe) a Norsat .7 single polarity model.

Anyway, this LNB uses a WR-75 waveguide interface, which wouldn't work with C-120.

I think Sadoun's site sells an LNB holder for prime focus dishes that will hold a 40mm neck LNBF. In that case he wouldn't need the Pansat Feedhorn.

I have, however, heard less than positive results from people putting an offset LNBF on a prime focus dish. Maybe someone who has done that can chime in.
