Here are photos of the system designed with assistance from
RFOptic, FISBlue, and DataPro:
Modules A&B take in the RF signal via RF Venue's Diversity
Fin antenna. Module C is the 2.4ghz IFB return from the cart
out of an RF Venue CP Beam. All three RFOptic modules are
capable of converting from 0.01mhz-2.5ghz, easily covering
500mhz & 2.4ghz. Module D is the SDI over fiber converter.
This is fed from the BNC output of a 4x1 Decimator Quad
Split. These four lines are then fed into the Break-In end
of the T-FOCA connector mounted on the side of a custom-
designed Pelican 1600 case. On the outside of the case are
the T-FOCA connector, three BNC connectors for Dual UHF,
and 2.4ghz Zaxnet on the left panel; and on the right are four
BNC inputs for SDI Video and one HDMI output from the
Decimator Quad View. On the opposite side of the Pelican is
an AC input. The entire case can run on either AC power or a
basic laptop charging battery with AC outputs.
At the cart end are a Break-Out cable assembly feeding the
opposite modules (A&B), receiving the signal and sending RF
out via SMA into the Zaxcom Mic-Plexer. The Nomad's IFB
output via SMA feeds the third module (C). Each module,
including SDI, powers via both AC and DC power.
