Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A mount for a feedhorn/LNA assembly in a parabolic satellite antenna which comprises a frustopyramidal platform having three legs and a thermally non-conductive mounting plate, said legs attached to the mounting plate at an acute angle to perpendicular to the mounting plate on bolts passing through the mounting plate at the same angle as the legs are raked before they are installed in said antenna and said legs attached to the satellite antenna further from the focal point than the legs are normally spaced whereby said mount is tensioned; said mounting plate provided with a counter hole on both sides of the mounting plate in alignment with each leg bolt for receipt of a means for spreading the load whereby the load by each leg is spread over a wider area of the mounting plate.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
The mount of claim 1 wherein the means for spreading the load is a washer.
Claim 4
Dependent Claim
23 words
The mount of claim 1 wherein the feedhorn/LNA assembly depends from the mounting plate on a plurality of J-hooks through an aperture therein.
Claim 5
Dependent Claim
28 words
The mount of claim 3 wherein the shank of each J-hook is threaded and extends through the mounting plate for attachment to a nut by which it depends.
Claim 6
Dependent Claim
24 words
The mount of claim 4 wherein the mounting plate is circular for easy and rigid installation of a weather dome having a circular base.
