<p class="MsoNormal">I am a new ham and a club member since I passed my Tech last August at the BVAC testing. I have also passed both my General and Extra exam about a month ago. I am working on setting up a HF radio for home. I have a ‘backordered’ IC-7300
which may show up one day. In the mean time, I am trying to plan for my HF antenna that will fit on my small lot. I think I can run an 40-20-10-6 OCFD (*MFJ-2010) in a slope from a tree in my front yard, with the feed point hung off a mounted on chimney,
and then on to a post above my fence in my backyard. I don’t have any trees in my backyard. Instead I have power lines across the back of the lot that I have to avoid.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I keep reading various comments and warnings about using a chimney for a mount. My chimney is in good repair, having been inspected and repaired during my home rebuilt after being flooded during Harvey.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is the center of the OCFD a light enough load to consider using my chimney as a center mount? Is there a right way to do that? Or should I ‘bite the bullet’ and setup a pole beside the chimney?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Any other antenna advice for a novice?<u></u><u></u></p>
