The 20 thru 10 meter dipole is constructed from stranded insulated wire available in most hardware stores. The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots used on lower frequencies.

The 80 meter vertical loop is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a 6 inch section of half inch diameter PVC pipe Article by W1TR

This article describes the design and simulation of a multiple dipole antenna for the HF band, using the software MMANA-GAL. The antenna will be designed to operate in the 10, 20, 40 and 80 m bands

The 160 meter ground plane is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoints / tiepoints use PVC pipe T-sections Article by W1TR

This article describes the characteristics of the Windom antenna and shows the results of several simulations made with MMANA-GAL, covering models optimized for the 20 m, 40 m and 80 m bands.

The 160 meter dipole is constructed from #12 stranded insulated wire available in most hardware stores. The feedpoint uses a section of PVC pipe Article by W1TR

The 2.6 Mhz M Dipole is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a T-section of PVC pipe

The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a T-section of PVC pipe. The coax loops through the PVC pipe to provide strain relief. by W1TR

The Arduino series of boards is currently the ideal choice for a satellite rotor controller. This controller uses an extended Yaesu GS-232 command set to control a Yaesu G-5500 Az-El rotor and four SPDT relays by W9KE
