SUBJECT: Indoor Antennas for HF & VHF/UHF
 I thought I would conclude the HF foil antenna here and move on to another
subject. Connections from the foil to the coax or BALUN are via the copper
tape. There are copper tapes available on the market that are used for EMI
applications. These tapes are expensive so if you can get a piece of some
of that tape from a buddy,it will work wonders for you.
 Otherwise,there is a trick with regular copper tape and the aluminum foil
that you can do.
 It's a simple folding technique that insures a good connection and yet
requires no soldering except for the coax / BALUN connection.
         ===========================================  Aluminum foil
              |-----------------------------------||
              | ====================================
              |------------------------------------------- Copper tape
 This folding method insures good contact on more than one surface.
 One warning, do not leave air gaps as it will have a capacitive effect.
 Solder doesn't stick to Aluminum foil very well.  With enough heat,you can
solder anything.  Too bad the aluminum foil won't hold up at that temperature
and neither will the solder.
 You now can solder leads to the BALUN or solder the coax direct to the 
opper
tape.
 For an indoor antenna,the foil antenna works rather well. It can out perform
a vertical and pull in the weak ones with ease. I think you'll find it one of
the most inexpensive antennas you can build yourself.
