Our New QTH - inside the community of ....

 


HOA rules  dictate operating challenges and in this situation the objective is to have antennas that can be heard but not seen. Currently I have six stealth HF antennas and while some are more effective than others, all are hidden including an outdoor vertical which has enabled me to work 40 countries on 40 meters.

 With a new Icom 7100 connected to rain gutters I was able to initially get on most HF bands, VHF and UHF with only a single radio. The gutters were loaded in a long wire configuration using an Icom AH-4 tuner.

 During the CQ SSB contest at the end of October  2016 I made contacts in 20 countries on 10, 15, 20 and 40 meters all using the gutter and the 100 watt IC 7100..

I have gradually upgraded the system with additional antennas and equipment . 

I  added  more HF antennas including a 40 meter and 20 meter dipole in the attic, a 17 M dipole hidden  on the roof of the patio deck and an outside "stealth" 27 foot ground mounted vertical  The vertical  is mounted on a metal stake against a tree in the back yard.  The vertical  is connected using 50 ohm coax via an LDG 600 watt tuner and uses a mobile mount (3/8 inch 24- thread). It is homebrew and consists bottom upwards of :

  • a 3 foot threaded rod - 3/8-24 (fine),
  • 4 ft  homemade loading coil wound  on PVC,
  •  a huster mobile base
  • topped off with a 17 ft MFJ telescoping whip.
  • A few radials supplemented  with a connection to the community provided ubiquitous metal fence make this a very effective antenna for 40 meters and higher bands. HOA rules help in this case. 

The vertical  has enabled 40 meter contacts throughout North America  as well as into Europe, Africa, and  Central and South America. This antenna is my most effective antenna for 40 meters and has allowed QSO's with several new countries many of which  were made with 120 watts SSB (Yaesu 101ZD).   A recently purchased 200 watt tranceiver, a used Icom775, and a new Ameritron ALS-600 watt amp have made getting heard in pilups somewhat easier.

The Icom 7100 no longer uses the rain gutter and now connects via the AH-4 tuner to a 100 ft. longwire that drapes over the roof and is nearly invisible. 

The rain gutter has been re-connected to the Icom 775/ Amp and allows operation on 75 meters with 600 watts.

I revised the feed point to connect at the back of the house and connected a wire to bridge an open section without gutters at the front of the house. The resulting antenna is effectively a longwire which wraps around the entire house but is open at the feed point.

The antenna uses coax to a 4:1 balun to ladderline and is connected with one side to gutter (long wire config ) and  the other side grounded to my fence/counterpoise.  This is my best antenna for 75 meters. A simplified diagram is shown at right.

 

 

 

No antennas are visible from the from the front of the house and in summary there are 6 operational HF antennas. 

  • 2 attic dipoles (40 M and 20M)
  •  an outdoor hidden 17 meter dipole
  • a longwire on the roof
  • gutter antenna 
  • vertical in tree

 

I am active on DMR using both  local repeaters and a newly acquired Shark RF Openspot.

 Using a Cellular data connection and the Openspot has allowed me to experience  mobile DMR using the extensive Brandmeister network. Dstar is available on VHF and UHF using the IC 7100 with an attic mounted dual band discone antenna.
