A Comtek phase system </B><B>using a microHam Stack Max switch</B><B> was purchased to replace it.  The elements are almost full size, as they were recently bottom loaded to go lower in frequency on 80M phone.  The verticals are made from push up TV masts with aluminum extensions added to the tops.  All verticals are supported by three levels of 4 point guying. Additional bottom loading is added to operate CW at times. There are at least 240 external radials.</B></div> </tD> <tD VALIGN=TOP><NOBR><div> <IMG SRC="073690e0.jpg" border=0 width="361" height="270" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> </NOBR></tD> </tR> </TABLE></U></B></div> <bR> </td> </tr></table></body>
