[HCARC] Large Six Meter Array and Tower Available

[Bill Tynan]

A friend, KM5PO, in the Dallas/Fort Worth area is being forced to dispose of his ham radio equipment. 

He is beginning with the tower and 6 meter antenna installation.

Someone please post this to the North Texas Reflector. When I try, it bounces.

Description is as follows:  

Universal 6-70 tower. 70 foot high.
Will need a three foot base section.


The existing tower is guyed at the 50' level with Kevlar cable and large turnbuckles attached to three trees. It routinely withstands 60 to 70 MPH winds. It is set with straps on the bottom section that unbolt from the three foot base section which was held in 1 cubic yard of concrete.


Has three 6M7JHV 6 meter yagis with 1 wavelength phasing cables plus an Array Solutions Stack Match switching system to allow selection of 1, 2 or 3 yagis or any combination. This allows you to select say the lower two yagis for higher than normal (all three yagis engaged) arriving signals and the switching system additionally has a 180 degree Phase Shifter which selects the highest yagi and the lowest yagi out of phase to receive the highest angle arriving signals in a short skip situation.


All three yagis are separately controllable with three Yaesu 800 rotors. The top yagi rotates a full 360 but the middle and lower yagi rotate about 270 degrees. 


All RF cabeling is LMR-600.The cabling (RF, Stack Match, Rotor cables) measure 50 feet from the base of the tower. All terminations are N-Style LMR-600 connectors.
