This has been the lowest maintenance rotator and the most reliable. Below are views of the beam on the ground and Andy from XX Towers fixing the 160' beam after ice storm.</B></div> </tD> <tD VALIGN=TOP><NOBR><div> <IMG SRC="0847a2b0.jpg" border=0 width="378" height="299" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> </NOBR></tD> </tR> </TABLE></B></div> <bR> <div> <B> <TABLE BORDER="0" CELLPADDING="2" CELLSPACING="1" WIDTH="732" BORDERCOLORLIGHT="#C0C0C0" BORDERCOLORDARK="#808080" FRAME="BOX" RULES="ALL" ALIGN="BOTTOM" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 256 ><NOBR><div> <IMG SRC="08fe6ad0.jpg" border=0 width="230" height="173" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> </NOBR></tD> <tD VALIGN=TOP><NOBR><div> <IMG SRC="095bcfa0.jpg" border=0 width="188" height="250" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> </NOBR></tD> <tD VALIGN=TOP><NOBR><div> <IMG SRC="093f1af0.jpg" border=0 width="241" height="175" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> </NOBR></tD> </tR> </TABLE></B></div> <bR> <div> <B> <TABLE BORDER="0" CELLPADDING="2" CELLSPACING="1" WIDTH="740" BORDERCOLORLIGHT="#C0C0C0" BORDERCOLORDARK="#808080" FRAME="BOX" RULES="ALL" ALIGN="BOTTOM" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 256 WIDTH="394"><div> <B>4SQR</B></div> <bR> <div> <B>The Comtek phase system is used </B><B>with a microHam Stack Max switch</B><B>.  The elements are quarter wave free standing aluminum conduit.
