This is a simple dipole antenna for FM broadcast. It can be tune for 88-108 MHz frequency range. It's very clear and easy to build. For more gain it can be stacked (2 or 4 antennas and used power divider for distributing RF energy).How to construct:
- Solder all copper pieces before attaching to the 1/2[inch] plastic T.
- The aluminum tubing is attached to the copper fitting with 2 self-tapping #6 screws, 1/2[inch] long, one on each side.
- The antenna element to which the ground side of the SO239(=PL259) is attached always points downwards.
- Tune the antenna by adjusting the lengt of the adjustable elements. Length in inches is equal to 2952 divided by the frequency in MHz
