The C140 feed OD is approx. 66mm. Scalar ID openings are typically 68mm. The original BV Scalar opening was specific to their custom feed assembly and had to be enlarged to accept any other manufacturers feed. Common retrofit in the 80's and 90's. I recall many "innovative" methods to secure...

Still have the project development PCB. :cool: No longer have the schematics.

Declination setting is only required if the dish will be motorized to move more than 20 degrees between adjacent satellites. Without declination setting the mount will not accurately track the arc. Also, no need to change the leg length or scalar position for optimal FD/FL if you only wish to...

Without modifying the mount to add declination, KU tracking outside of the apex of the arc will be impossible. The narrow beamwidth of a 10 ft reflector on KU requires precise arc tracking. This dish pre-dates BUD owners receiving KU. My best guess would put the vintage of this dish around 1982...

Your dish has great potential, but will require some modifications to accomodate changes in technology and usage since it was manufactured 40+ years ago. As I suspected, this is an original Birdview LNA type feed. This type of feed is no longer in use and unsupported by receivers in use today...

I don't see any declination setting on the mount photos. You probably will find that the installer placed spacers on a few of the bolts between the mount and the reflector. If there are no declination spacer shims, the dish would accurately track c-band satellites within approximately 30 degrees...

The mount on this Birdview appears to be an early polar mount type (not a horizon to horizon) with a 36" linear jack (actuator) arm. The actuator may still work, but I recommend that you tear it down, remove the rust, reassemble and lube. Apply 12 VDC (car battery?) to the DC power terminals to...

I may have misunderstood the poster's question, but thought he was installing a C-band prime focus.

I also do not understand the reason to use the USALS protocol to calculate positioning with a Reed switch pulse count linear actuator. Use the sun's position and feedhorn shadow to determine where the dish is aimed. Simply motor the dish until the shadow of the feed falls on the vertical axis...

Did you try and test the voltage under load?

The Titanium C2-PLL has been out of production for several years and is no longer available in any market. Sub 3700 MHz filtering is not used in the North America market as 5G N77 low band and high band are both in use in our region. You might look in the Australian marketplace for PLL LNBFs...

I've replaced hundreds of those damaged and missing cover locks with nylon ties...

A repoint service call for a small KU dish at a commercial location near a major US city will be a minimum of $500.

If the interference times do not line up with the solar outage calculated times and duration, then it would be local. Have you identified the frequency and strength of the interference? I would set-up a spectrum scan from 3.7 - 4.2 GHz and capture and hold active carriers that are...

Most likely you are experiencing solar outages, when the sun lines up directly behind the satellite, twice each year (spring and Fall). This will happen for a few minutes each day for a week or more (up to 10 ten minutes at the peak). https://gi.globaltt.com/Tools/ToolsSolarOutage.aspx
