A 12 AD-UHF
Active directional antenna with integral booster amplifier. The A 12 AD-UHF
has a switching bandwidth of 24 MHz which can be adjusted within the range
of 450 - 960 MHz. The integral booster amplifier directly receives the necessary
DC power via the antenna cable from the receiver. Suitable for Sennheiser receivers
EM 2003-TV HDP, EM 2004 UHF, EM 1046 UHF, and EM 203 UHF.

* The EM 2003 and EM 2004 receivers limit the current to 25 mA max. at
approx. 8 V, but we would nevertheless recommend the use of the A 12 AD-
UHF antenna since the only reduction in quality is that the intermodulation
attenuation will be reduced to ≥ 74 dB.
