Ideal length of a dipole for SWL

edited January 1970 in Homebrewing
Hi, I want to setup a dipole antenna on my terrace for SWL (mostly for HAM bands and air traffic).  What length should be ideal to cover both 20 and 40 meter bands ??  I need to keep the length minimum as I live in a rented apartment and the total area of the terrace is around 12 meters X 12 meters with no trees or a y other support around. Also, do i need to further put this dipole higher from the terrace?? or can I put close to the wall?? (Actually I dont want pipes or fixtures on the terrace, want to keep it minimum..) Please suggest any other ideas if you have.


  • FYI<br /><br />could only manage to put 33 ft total length dipole for 20 meter band as I stay in a apartment and my terrace could fit in only that much of length.  Reception on HF has greatly improved with the dipole.
