NO!!!NO!!!
CAUTION !
2.3 Using Ground Radials
Do you see how the transmitter is mounted right next to the house? It is not above all buildings, the antenna is not in the open air, also look at the antenna, it is right up against the siding!! NO!!
Even if this does work a little, range will be very low in the direction of the house.
This transmitter needs to be moved up so that the antenna is entirely above the top roof line, preferably at or near the peak of the roof.
Remember if you cannot get one location to work well you may need to try another. We will talk in the troubleshooting manual about how to determine if you have a good ground or not.
Be careful of power lines, stay away from them for safety reasons. Be sure to follow safety laws and procedures when climbing, do not mount the transmitter in a unsafe location.
We have referred to buried radials earlier. In general for a radial to be effective the length should be more then the height of the antenna tip is from the ground. A radial is just a wire going from a center ground rod outward.
Elevated radials
First of all be aware that elevated radials do increase radiation, and may not be approved should you be inspected by the FCC
Note the direction of increased signal. More then one radial can be used.
Buried radials
There should be no problem with the FCC concern- ing buried radials, metal in the dirt does not radiate.
For more Information see the Legal section.
3. Installing the Control Wire
This is the wire that connects between the studio and transmitter. The kind of wire used is important. We recom- mend 2 pair, #22, shielded, UV protected, outdoor wire. Several hundred feet can be used with a voltage drop of 1- 2 volts at the most.
Belden 8723 is the 2 pair #22 wire we recommend. Cat 5 outdoor shielded wire can also be used, though it is smaller, #24. Cat 5 has 4 pairs so it is possible to connect three of the pairs together for power to help allow for the smaller size.
Connect the Shield drain (ground connection) at one end of the cable only, usually the transmitter end. There is a terminal marked GND that can be used to ground the shield drain.
Good grounding is important for safety lightning protection , be sure to follow any national and/or local electrical grounding codes.
