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 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
