Signal Boosters – Can Pose Problems!

EWA is often contacted by members who are experiencing interference from Bi-Directional Amplifiers (BDA’s). As a reminder, licensees may use BDA’s only on those frequencies for which they are authorized. FCC Rule 90.219 provides an outline for operational use, type of signal boosters, maximum ERP and their emission limits. Licensees should also note that Class B signal boosters can only be used in confined or indoors areas, or remote areas where there is little risk of interference, and should be aware that if they intend to use BDA’s, they are responsible for correcting any harmful interference.
