So I had some time today to play with this. I have seen several posts about using an SL5 or SL3 on an 18x20 dish. Here are the results I got. I used my old trusty peaking LNB so I knew I would get as good a signal as possible.
Normal signals on the 99, 101and 103 in my area are 95+ on most transponders.![IMAG0069_640x480.jpg IMAG0069_640x480.jpg](https://satguys.nyc3.cdn.digitaloceanspaces.com/data/attachments/46/46370-5c4508e99f9520a53906d90f9cd82060.jpg)
