You are using a wi-fi antenna (2.4 / 5.8ghz) for
29mhz band? If it is true, use a ghz antenna on the mhz range as the same as
nothing, because the wavelength of 2.4ghz are 13cm and the wavelenght of 29 are
10meters, and if the dipole have some harpin, gamma math or some impedance
adaptor, on 29mhz as the same as to do a shortcircuit, and you can damage the

while executing USRP examples
1)As suggested by Matt ,we have purchased the Antennas
(Specifications again for reference).
2) Now Can we change the
frequency range for the below specified examples fsk_tx.py , fsk_rx.py
and nbfm_ptt_quick_and_dirty.py other than 29Mhz ?
3) Since we
have already purchased the antenna's , is there any way that, with minimal
modifications we can use the same Antennas?
Please provide some
solution on the same.
Operating Frequency 2.4~2.5 & 4.9
& 5.15~5.35 & 5.725~5.85 GHz
Polarization Type : Linear
of Radiation: Toroidal
Peak Gain 2.0 dBi Typical For 2
G 4.0 dBi Typical For 5 G
Impedance: 50 Ohm
V.S.W.R. 2.0:1 Max.
Swivel : 90
