If we had only one antenna to use for monitoring at RadioLabs, it would be the Discone antenna.

While the specifications of this antenna are only for 25 - 1000 MHz, we have found that this antenna is actually good from AM broadcast band and all the way through the 2.4 GHz band. It's a completely amazing antenna with performance that will blow your mind, all the way down below the AM broadcast band.

While you might not be really impressed, we sure were, especially considering that this antenna costs less than most single antennas.

This antenna is rather large though and requires a little room on the top of your house or a pole. The vertical elements (the ones which point down) are pretty long, which explains why this antenna works so well.

This antenna is even good for transmitting from 25-1000 MHz if you are into 2-way communications. The RL-Discone antenna's design was for receiving, but at the same time it is good for transmitting throughout the entire VHF portion of the amateur radio band.

Frequency coverage: 25 to 1000 MHz
Bandwidth: 9.5 GHz discone design
Gain: Unity +
