Excalibur 2 project. Antenna cleanup

Today I began to clean up the radio site at my friend Paul's (AA4XX) farm. This site is affectionately known as 'Excalibur'. This name stuck when we first deployed a 5 element full size beam for 20 meters. The tower was struck by lightning about 2 years ago. This started a fire in the shack causing internal damage to the shack. Luckily the exterior of the shack survived and is in excellent condition thanks to a coat of paint that Paul and his son gave to it.

I began by clearing away all the wires lying about the area. Many of these wires have been on the ground for the past 2 or 3 years and are thus embedded into the ground.

I also pulled down the existing remains of the wire antennas. These wires were deployed using weed eater plastic cord. Interestingly after 3 years this weedeater plastic is still very strong and does not appear to have deteriorated at all.

Much of the wire was from a topband radial system that Paul deployed. These radials consist of aluminum fence wire and is excellent and inexpensive for antenna applications.

Aluminum home brew wire feeder. Still in good condition and will be redeployed.
