We only need 250-300 feet and 500 ft., is pushing it. The FCC will bust those who have these .5 to 5 Watt systems with dipole half wave antennas sticking up in the yard or on the roof. if they are hanging Antennas up on the house and transmitting more than 100 yards there will be a big target on them. Antennas should be kept out of site, in the house, not on the house or in the yard. FCC PDF |

Types of Antenna
Here are some common antennas:
1. 1/4 Wave Ground Plane
2. The Dipole
3. The Folded Dipole
4. J-Pole
5. 3 Element Yagi Beam
6. Flexible dummy loads (often called Rubber Ducky, or a Loaded Vertical)
Benefits of them
The antenna can be a major source of interference. If the length of the antenna is not properly matched to the transmitter, it can sometimes generate unwanted signals that are transmitted more effectively than the desired operating frequency and its contents.
