[QUOTE="Channel Hopper, post: 1077285, member: 175144"] Further to your post and the additional holes. These could be used for the even number petalised (four feed arm) systems such as Channel Master / Wineguard centrefed antennas and the Prodelin 1252 model, though you will need to remove/ adapt the existing brackets from 120 degree spacing to 90. Many designs of this type, in particular Chaparral, use a second bolt hole on the scalar to lock the feed into the pattern, preventing twisting and a different focal point as a result. Just a thought - It might be worth have the feed clamping attachments displaced by 90 degrees in the manufacture, running in line with boresight which offers two advantages, no twisting and on smaller dishes, a minimal shadow of the electronics if the scalar ring is discarded.
