[QUOTE="Family_Dog, post: 965828, member: 82"] [i]1. Will it be effective if positioned inside the ceiling only and not outside. Will it then still have to be grounded?[/i] # The higher the better, depends on signal strength in your area. Will not work too successfully under a metal roof. [i]2. If outside: do I use surfix cable to ground it, quite sure single core surfix doesn't exist :thinking:[/i] Braided grounding wire is available from any electrical supplier, ground it to metal water pipes if available otherwise smack a 6' grounding rod into the earth. Keep the grounding cable as straight as possible, avoid sharp bends. [i]3. Is orientation important or should it just be installed vertically[/i] Most FM transmissions are vertically orientated, localised "gap-filler" antennas might be horizontally polarised but assume it to be vertical. -F_D [/QUOTE]
