Antennas & Feedlines

These items are usually in stock for immediate delivery at no additional shipping charge when purchased with an SDR receiver.

Please note that portable antennas are designed for strong signal work, and are a compromise over station antennas.
For the best performance, we recommend using outdoor station antennas.
The below antennas are the best portable solutions we have found so far. Use of Ferrite Beads is highly recommended when using portable antennas.
