[TenTec] Apartment antenna help

[GARY HUBER]

Consider using a LDG or similar end fed wire automatic antenna tuner at the window with counterpoises for each band. A single quarter-wave (on the lowest band used) wire should provide good results.

  Subject: [TenTec] Apartment antenna help


  Greetings all,

  I'd like some "brainstorming" help on an antenna for my dad. He is on the 
  third floor of an assisted living apartment facility, and we've been trying 
  to figure out if we can get him on the air from there (even on a limited 
  basis). Dad has been trying some indoor antenna setups (such as the Hamstick 
  type dipole arrangements) but apparently to no avail. I suspect this has to 
  do with the construction of the building (i.e. iron frame etc.)

  I have talked to the head of the maintenance department at the facility and he 
  seems to be willing to work with me on an antenna, but obviously it needs to 
  be as unobtrusive as possible as well as require as little alteration to the 
  building as possible. Since dad primarily like to operate 40/30/20M, what I 
  am currently thinking as a solution is a 22' wire (either horizontal or 
  vertical) attached to the outside of the building with a bead of clear 
  caulking or RTV. I would need to get this through a window, so I am 
  envisioning using a short piece of a "sandwich" of 1/2" - 3/4" wide thin 
  copper strip/flashing with thick plastic tape on either side so it can 
  (hopefully) be formed so that the window can be closed with it in place. I 
  realize that there would probably be some coupling to the window/frame as it 
  is aluminum. The 22' length mentioned is chosen as I am of the impression 
  that it is a good compromise length that is easy to load on 20-40M. This 
  would be balanced with a 22' counterpoise along the baseboard inside and fed 
  via an SCG (237?) autotuner placed where the antenna comes in through the 
  window. (Hope I'm making sense here with all this....) Another possibility I 
  have considered would be something similar to the B&W/MFJ apartment antenna 
  but with the matching network relocated to inside the building (again 
  possibly using the SGC autotuner along with the requisite counterpoise).

  What is the possibility of this actually working (obviously on a rather 
  limited basis)? Any comments or suggestions? BTW this _is_ Ten-Tec related as 
  dad would be using this with his Delta (probably at quasi-QRP levels of 20W 
  or less due to the possibility of TVI etc.)
