Helix Building and tower
RF Signal and data transmission lines going from transmitter building to helix building.
Helix Building showing feed up to top radials of grounded tower. Tower is for support only, not an electrical part of the antenna.
The output from the helix to the antenna feed.
Signal feed up to one of the top radials. (Not electrically connected to the tower)
With the grounded tower antenna, all the top radials are insulated from the tower. They are all interconnected to the radial receiving the RF signal from the helix. The tower support guys are not insulated.
Another view of the top insulators.
Notice the six guy wire to three anchor arrangement.All Omega towers were painted alternately red and white. Only Australia started with white at the bottom. If you know the reason - let us know.
