Topband: Antenna Question

[wa4fki]

I want to build a small 4 square but pretty effective receiving antenna. I read somewhere where 4 10 foot pieces of EMT could be used, how could I phase them without of a lot of trouble? I want to use this antenna to get general directions where stations are located. I feel this antenna would be an asset when monitoring "intruder stations."

I have recently become the Region 2 Monitoring System Coordinator, using something like this would help determine a general direction where the intruders are coming from. I also see the articles in ON4UN's handbook describing a simple 2 element end fire rotary antenna. If anyone had every constructed this 2 element rotary array, can the boom be shortened a little without causing big problems. Mainly would use it from about 3.5 Mhz and up.

I would appreciate any reports of intruders into the 160 meter band including "fish net" beacons. Email me with any information, it would be greatly appreciated and in the long run may help ham radio in general.
