Depends on if you're trying to transmit or receive.

Quote:

A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources. Directional antennas provide increased performance over dipole antennas – or omnidirectional antennas in general – when greater concentration of radiation in a certain direction is desired.

I want to get a full duplex SDR and design some custom circuits. Maybe some day make a full duplex SDR from scratch.

Would like to experiment with masers, and receiving/analyzing ELF traffic.

Why do you want an ELF radio to work with masers? I also doubt that you have the space for an ELF antenna.
