The ZR-3 is designed to be mounted 1 or 2 feet above ground. It can also be elevated, such as on a roof or balcony, or in an attic or garage, or mobile. The ZR-3 weighs about 24 pounds. Each band is easily tunable. The preferred feed is at right angles to the center radiator using the supplied Force 12 B-1 balun, which has been convenient for most installations.
Optional feed is from the bottom, up through the center radiator.
Although the ZR-3 can be installed in a variety of locations close to people, caution should be used to be sure the energy field is not in excess of FCC regulations. There are no traps, loading coils, toroids, or radials. The 2 meter single band is identical to the photo, simply minus the inner rings. The antenna can be mast mounted or placed on a table using the optional flat plate for temporary use. The rings on the top and bottom of the center radiator are not capacity hats.
