Stealth 9310 Automatic Tuning Whip Antenna is a lower cost version of Type 9300 military antenna systems The antenna is constructed using a 4-way electrical conduit junction box and 3/4″ PVC electrical conduit as shown above. The length of a full-wave antenna is given by the formula 1005 / frequency in MHz = total length of the loop. So in this case, we want to build an antenna for 6 meters, 50.110 MHz. 1005 / 50.110 = 20.06 feet. On 20 through 10 meters, the antenna is 1/4-λ long. On 6 meters, the antenna is much too long to tune as a 1/4-λ radiator, but not too long to tune up nicely as a 1/2-λ radiator. With the whip fully extended, it's only a matter of some experimentation to find a "sweet spot" for 6 meters.
