FV-HD30 Coax Length

[mike_b]

Hi,

I live about three miles from the TV transmission sites in my small town. Surprisingly, the CBS station is transmitting using a directional low power transmitter and I am unable to receive it with an antenna. But fortunately, they have almost completed an upgrade to a non-directional transmitter with increased power. I plan to try the FV-HD30 when their upgrade is complete.

I would prefer to mount the FV-HD30 in the attic. Considering the short distance to the transmission sites, would I really gain anything by mounting the antenna on my roof? It would require a longer run of coax to mount the antenna on the roof. Is it best to mount the antenna on my roof using 100 feet of coax, or in my attic using 50 feet of coax?

Good morning mike_b,

This answer greatly depends on the materials in your roof and other surrounding obstructions. In general, mounting an antenna indoors or in your attic can cut your signal down by 50-90% depending on those materials. Think normal wood, insulation and shingles at 50% and a metal roof at 90%.

Being that close to the transmitter you should be fine having that antenna in the attic, but it is dependant on those obstructions.
