Custom Project
One of our customers wanted a pre-packaged system that would work easily at distances to 300 feet and beyond. We were up to the challenge. The sensor has been refined over a period of years and really doesn’t leave us much room for improvement easily. Adding a hi gain directional antenna to it is possible but doesn’t seem very elegant. Instead, why not add an antenna and preamplifier to the receiver, on the ground, where it’s a bit easier to work with? And that is exactly what we did.
Apologies are in order for the less than spectacular pictures. But its tough to get a good photo when the sensor and receiver are 325 feet apart. That’s right, 325 ft and still going strong. (We ran out of space in our field test!) Below is a picture of the sensor at the far end of the field temporarily propped up on a folding table and barrel.
Below is a photo of our quick and dirty setup. We tossed the antenna, preamp and receiver on a card table along with our oldest laptop to log the results. No dropouts over several hours operation.
