Built a 2m slot antenna out of an old Dish Network 1000 dish. After cutting slot, dish has little to no physical stability. Designed and printed small blocks (1/2" wide, 1/2" thick, 2" long) out of PETG to support, attached with some 6-32 machine screws. Tunes up alright on 2m. Going to use this for APRS, so aiming for 144.39 -- decent swr currently of 1.86, going to adjust the feedpoint and slot length a bit to see if it can get better.
