Author Topic: Antenna & Aluminum siding - questions  (Read 809 times)

Hi All,
   Would like to put up an inverted L for low power QRP work.  The vertical segment would run up the side of the house using insulated wire and standoff insulators then turn to the horizontal segment running out to the yard sloping a bit to a small tree.  Feedpoint would be at the base of the vertical segment with a AH4 or similar at.  My question is whether or not the close proximity of the vertical element to the house aluminum siding will result in problems with tuning the wire.  Any comments and/or help would be appreciated.  Due to restrictions, this is about the only "stealth" antenna I can put up.

Thanks - Scott W3BUG

Of course it should matter.  Ugh.  Aluminum siding is the bane of ham radio (I know, I've had to deal with it also).

However, if this is all you can do, I'd recommend using well insulated wire and staying as far away from the siding as possible.  There is no question the siding will effect the way the antenna works, but performance may still be satisfactory -- no way to know unless you try it.

I would try to position the vertical segment of the antenna at one of the corners of the house, to minimize the amount of metal in close proximity. This is in addition to the suggestion of keeping the vertical segment as far away from the house as you can.

What is the planned overall length of the antenna, and how high will the horizontal portion be? Longer and higher is better of course, but any antenna is better than no antenna!
