The dish pictures were taken prior to installation of the new feed support.
2mfeed1 and 2mfeed2 are with original wide spacing, which resulted in inadequate illumination.
144feed1 and 144feed3 show current DE to R spacing.
The filter is placed after the feed mounted preamp and before a second stage preamp.
quadrl.jpg shows the network analyzer picture of the DE return loss. DE has sleeve balun, but no impedance matching.
