160 Meter Antenna
With all the other shack and antenna building efforts going on, I was late to the party on 160M.  When the K5D (Desecheo) came up, I was upset that I had no antenna for 160.  I was keen to get back on 160 and get my DXCC for that band.  I built a dipole and laid it on the ground.  I managed to work K5D but not much else.

I started with a rather anemic vertical antenna with an antenna tuner at the bottom.  The wind really made things difficult and blew the antenna down.  The fact that I kept burning up the antenna tuner didn't help.  There are very high voltages in a 160 antenna tuner for a shorter vertical antennas.

I decided that I needed to go to a very robust antenna that would survive the weather and not suffer from erectile dysfunction.

So, I looked around and went to Zero-Five antennas (http://zerofive-antennas.com).  Tom builds them strong and to last.  The following graphics show the antenna and a close-up of it's base.  This is a full size quarter wave 80M vertical with 60 each 65 foot radials.    Click either graphic to enlarge.. 

  I' installed a vacuum relay at the top of the antenna which is remotely controlled from the shack.  It switches in or out another approximately 65 feet of wire to form an inverted L for 160.   The horizontal wire goes over to my tower and then back down.  Almost an Inverted U.

My SteppIR DB-18E on the new tower provides capacitive top loading.  By changing the frequency of the SteppIR I can tune the 160 meter antenna from 1.8 to 2.0 MHz. making the antenna usable the entire 160M band. 

This antenna works fairly well.  I am competitive in DX pile ups and met my goal for that 160 season and finished my top band DXCC.  With the cards in hand the ARRL awarded me 160M DXCC.
