RF HEAD CONNECTORS

IF Interface and AUX Power
The TNC, or Triax, IF connector inputs the
diplexed 70 MHz, inter-unit control data, and
DC power for the RF Head when Belden
1694, or Triax, cable is used. If RG-59 is
used, then DC is input from the Aux Power
cable via the Aux DC Power input. (Refer
also to Figure 21, Detail 16.)
Antenna Polarization
This connector (if configured) receives the
antenna polarity control signals from the
Control Unit. Both NSI and Radio Waves
antennas are compatible, as well as others.
See Table 12 & Figure 19 for NSI details.
See Table 13 & Figure 20 for RWI details.
(Refer also to Figure 21, Detail 12.)

Pan / Tilt Power (from Control)
This connector (if configured) inputs power
from the Control Unit, which is then passed on
to the RF Head.
See Table 9 and Figure 16 for 120 VAC P&T.
See Table 10 and Figure 17 for 12 VDC P&T.
(Refer also to Figure 21, Detail 14.)
To Pan / Tilt
This connector (if configured) outputs signals
and power for the Pan & Tilt unit. Refer to
Table 11 and Figure 18 for cabling and pin-
outs. (Refer also to Figure 21, Detail 13.)
RF Output
The RF output is via a Type-N connector
located at the center rear of the NewsCaster
VT2 RF Head, and carried via a 50 Ω low-loss
coaxial cable to the antenna. Turn the cable
connector clockwise, while keeping it in line
with the transmitter connector. To avoid
unnecessary connector wear, do not allow the
cable to rotate while you connect it to the
transmitter.
