Hi, I tried to use my gnuradio catch some radio signals in the air with the script ./gnuradio-examples/python/usrp/usrp_wfm_rcv.py, but all we heard is just some noise in FM frequency band(about 90MHz~110MHz), so we guess maybe need an antenna to get a stronger radio signal. our USRP has two daughter boards: basicTX and basicRX. And we mailed to Matt Ettus, here is letter and his reply (say sorry to Matt Ettus for publishing this letter):
-----------from here-----------------
We've got 3 USRP packages ( also 3 basic RX-daughter boards and 3 basic TX-daughter boards). However, it comes without antenna in the box. We want to know that if we are required to buy antenna from you if we want to perform experiments between those USRP devices? If yes, which mode is suitable for us? Thank you.
Antennas are not included in the purchase. You will need to get your own. We do not sell antennas which match the frequency range fo the basic rx and basic tx, so you will need to purchase those elsewhere. Thanks, Matt Ettus ----------to here------------------------- We've checked the interface of USRP, its SMA Female, and nearly all the antenna's interface for wireless which are sold in Fry's Electronics is SMA Reverse Plug. So I guess a adapter from SMA Male to SMA Reverse Jack will connector the USRP's RF end to an antenna. Is anyone has any idea of the antenna, or where we could get such adapter or some link of website where we could buy antenna suitable for BasixRx/Tx daughter board? Thank all for any help, Dong _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
