TITAN MISSILE MUSEUM DISCONE ANTENNA
WB5DYG UHF REPEATER

Located south of Tucson, AZ the Titan Missile Museum offers a unique look at cold war history. From 1963 to 1987 54 Titan II missile sites across the United States remained on alert, their primary mission being deterrent of global nuclear war. From their underground silos, the Titan II missile sites could launch a 9 megaton nuclear warhead to targets more than 6300 miles away. What was once a top secret installation has now been preserved for history as a National Historic Landmark. It is well worth the trip for the tour of the silo alone!
Communications of course played a key role in the mission of the Titan II missile sites. At the Titan Missile Museum the Green Valley Amateur Radio Club affords the opportunity for amateur radio operators to utilize the original Collins Radio HF discone antenna on the site. At nearly 80 feet tall, the discone become operational in July of 1963 and served until it was deactivated in 1982. The club has generously provided coaxial connections to the antenna and a picnic table to set up the rigs on. Simply sign in at the museum, drive to the overflow parking lot southwest of the antenna, plug in, and enjoy! On a beautiful fall day Scott, KE7MRO, and Ron, WB5DYG, made the trip and spent several hours enjoying the opportunity to operate with this great piece of history. We worked hams all over the United States as well as contacts with Greece, Buenos Aires, Slovenia, and Cuba. In fact, Scott started several pileups once other amateurs got wind of where we were and heard the descriptions of the antenna! Special thanks to George, AD7DH, who stopped in to greet us and was also our tour guide on the fantastic tour of the Titan II Missile Site.

Prior to operating on the antenna, it was checked out with an MFJ-259B Antenna Analyzer. Those results for 40 through 20 meters are pictured below. The antenna is basically below 2.5:1 SWR across these bands with 12 meters slightly above. Your mileage may vary... always be sure to check out any antenna you plan on using with an analyzer or SWR bridge prior to transmitting on it.
