FM antennae question


I am using the Fanfare FM-2G dipole antennae and I just had my brother move it to the peak of my roof; it is attached to the gable end fascia. I have very large fascia, he mounted the antennae to the lower part of the fascia so the first six inches of the antennae is against the fascia before extending past the roof. Could this cause any performance loss or am I going overboard here???

The higher that you get the antenna and the more "in the clear" that it is, the better the performance you will obtain. If you have nearby conduit in the wall or aluminum siding, this WILL "detune" the antenna. That type of a situation is known as a "nearfield reflection" and alters the antenna's feedpoint impedance, bandwidth, radiation / capture angle, etc...

Antenna's of this design ( base loaded ) REALLY need to be out in the open and above everything else to obtain OPTIMUM performance. If you are pulling in all of the stations that you want to at full quieting, i would not worry about it. Otherwise, there is room for improvement ( as slight as it may be ) depending on your specific situation. Sean
