I was looking at the Beam Box. There are several of these around but never seen or used one. Are there advantages over the newer home antennaes or are the newer (FM 360) ones better?
When it comes to antennas of all types there is no substitute for full size, correctly tuned antennas that are correctly matched to the feed line.
The higher the antenna the more signal it will receive.
The BIC Beam Box antenna uses electrically shortened elements and may not be put high on a shelf because of the need to reach the controls on the front. The Beam Box, like all antennas, is sensitive to surrounding conductive objects.
These are limiting factors in how sensitive of an antenna it will be.
The Beam Box is able to electrically vary its directional signal pickup pattern, to favor certain directions or reject signals or noise from certain directions.
Their prime application is for moderate to strong signal areas.
Again with RF signal reception reception it is location, location, location and sometimes orientation.
Since most of the people in the USA live in moderate to strong RF signal areas, even just a random piece of wire may provide enough RF signal strength for the stations of interest.
The FM-360, as the name implies, is an omnidirectional antenna, that is it receives signals from all directions. It does not have any gain, it is not more sensitive than a dipole antenna, but it is usually installed outside and higher than an indoor dipole antenna. This allows it to capture more signal strength.
The antenna that onwardjames is describing is in the shape of a variation of the Slim Jim antenna which is a variation of the j-pole antenna.
See the picture below.
The actual Slim Jim design may offer better performance if the correct dimensions are used and correct feed line decoupling is employed. The over all length of the Slim Jim antenna is about 84 inches.
For a simple antenna, it is hard to beat the venerable rabbit ear antenna. It can offer some gain broadside to the V of the elements and the element length may be adjusted to produce an antenna that is resonant on the FM broadcast band. The elements remain straight and out in the open. The angle of the elements may be adjusted to enhance the desired RF signal pickup direction.
It is possible to orient the antenna to favor the station of interest or to null unwanted signals or noise.
