Quick Antenna Tips

There are two basic antenna types: directional and non-directional (omni-directional). Directional antennas are typically Yagi type, non-directional are dipole type.

The reception pattern of a directional type antenna is shown below, left. The pattern for an omni-directional antenna is shown on the right.

• The more elements on the antenna, the better the gain and effective range (they are also less portable!).
• VHF systems are line of sight; the higher the antenna is above the ground, the better the range.
• All ATS antennas include a standard length coaxial cable; longer lengths are available.

We offer a complete line of antennas for radio tracking and all include a receiver cable. We can give you advice if you’re not sure what kind to use.
