Hey all,
I’m slightly confused. I’m trying to find an antenna to use with the
basic TX/RX boards to transmit and receive over the air. What frequency
ranges do the basic TX/RX boards do? After checking the wiki, it just
says “baseband.” Doing some research, I think it means a band of
frequencies starting at 0 to the highest frequency. Up until now I’ve
just been using coax, so it hasn’t really been relevant. So what’s the
highest so I can determine what antennas to purchase.
Thanks!

Apparently when I put that page together I never noticed the description
here:
http://www.ettus.com/downloads/miscdboards_v3b.pdf
Which states the Basic series of cards are 1MHz - 250MHz (not baseband
due to the transformer coupling).
I’ve updated the wiki pages to state the correct frequency range and
description.

that the Basic boards can go as low as about 100kHz.

Noted (both mentally and on the wiki pages). Thanks!

George, I don’t think you really want to be using basic tx/rx to do on
the air transmission. They really weren’t designed for that, unless
connected to some kind of external filters and/or amps.

It means you cut the element to the right length to resonate at the
center frequency you want
