dam santa

[VE7MGF]

the wire antenna came down Christmas night so i get to build a new one
my thinking is to build a shortened 160m dipole
the apex is about 40 ft with a leg of 62ft
going to feed it with 450 ohm and a tuner
there is no way to put up a full size dipole
so if i insert a loading coil in the middle of the leg to make up the shortage in length
is this a reasonable solution to getting an antenna that will go from 160m to 6m
and yes i downloaded antenna modeling software couldn't figure how to run it
i know there are people on here that have much more knowledge than i do on this topic
thanks for any info supplied

If you dam Santa, he'll explode of toxic sewage build up.

ya well next time i guess reindeer are in season all year

If you dam Santa, he'll explode of toxic sewage build up.

I thought it would be an explosion due to an overdose of milk; word is he's lactose intolerant. (At least Scott Calvin is, or was)

So, I wish I was more helpful with the antenna.

i figured that if i let the wisecracks go for awhile before i try to get back to the topic posted

To clarify things a bit, are you proposing to stick a loading coil on just one side of the dipole?

If you're planning to use it on all bands from 160 through 6, such a construct - when fed with ladder line - must be a half-wavelength long at 80M. This length is subtracted from the total linear space available then the remainder is halved and used as the approximate length of the two end stubs. Once you have that figure, you can plug the main dipole and stub lengths into one of a number of online loaded-dipole calculators and get your coil dimensions.

You don't need traps with this approach...just loading coils.

i want to put a loading coil (wraps of magnet wire on a plastic pipe ) on each leg about 3/4 of the way to the ends
to make the dipole electrically 1/4 wavelength long per leg

If this comes out like I want it:

--0--------[==]----------------------(++)----------------------[==]--------0--

Insulator, stub, coil, 1/4w (@80M) wire, center insulator/connection to ladderline...repeat for the other side.
