6. REMOTE ANTENNAS
If the screw in whip antenna provided with the R33 cannot be used due to receiver location, it will be necessary to use
a remote antenna. Two antennas will be described; one made from coaxial cable and the other from a modified CB
antenna. The coaxial cable antenna is the simplest and has worked well in many installations using our equipment. The
coaxial cable is available from an electronics parts store or at Radio Shack. See figure 5 for construction details.
If you decide to use the modified CB antenna, buy only a long (108” antenna. The shorter CB antennas use an induc­
tive loading coil to artificially increase the length. These will resonate at the CB frequencies only and will work poorly
with the R33. See figure 6 for construction details.
INSTRUCTIONS
1. Remove 7 feet of outer sheath. Use care to avoid damage to the braid.
2. Loosen the braid by pushing it back over the center conductor.
3. Open the braid at its junction with the sheath and pull the center conductor through the hole.
4. Flatten the braid and fold it back along the sheath. Tape the braid to the cable using plastic insulating tape.
5. For best results, try both horizontal and vertical orientation of the antenna.
