Well I just visited Angel Electronics and Save and Replay outlets. About 15 min drive from my home here in Mississauga. They all have antennas, cables, splitters, power inserters, connectors, etc. However, they do NOT have important things like FM Traps and UVSJs.
Their sources have dryed up according to them. They cannot get those parts. Suggestion was to try Amazon or Ebay.
There was a time when those parts were locally available. A lot of those shops have disappeared as have FTA suppliers.
OTA, CM4221HD, 3410 amp, 4 way split, HW-150 PVR.
FTA, Openbox S9, 33” dish, PLL LNBF. Stab 90HH.
