small shortwave antenna
 

I am livign in an apartment, so I cant transmit (no towers and what
not) so I am looking for what would suit my needs best for HF and
shortwave recption in general

I have googled a bit and havent found much in the way of easy to build
or easy to obtain parts to build antennas

any help would be really appreciated
cheers

You sure you googled?

A metal slinky with a MLB on the end and feed your radio with
coax. Use inside or out. Collapses down to a very small package when
not using and works amazingly well. Use it vertically or horizontally.
About the most simple and most effective HF ant. you could use for
apartement life. Dont waste your money on an active antenna, they
are notorious for picking up all sorts of electrical noise, sometimes to
the point of the radio being unlistenable.

It stands for Magnetic Longwire Balun. Its really not a balun ,
rather it is more of a transformer to match the impedance of the
antenna to that of the radio......... roughly 50-60ohms. Its usually
a torroidal magnet with 2 windings, a primary and a secondary.
They work very well for their intended purposes. They are 35-45$
but are worth it IMO. Do a google search for them and read all
about them.

screw $45-$60 for a MLB! you can wind it yourself for $5. the info is
out there. i am sure that someone here would help. CW has it on his
site, maybe he will check in with the address.

I have done that and my SLINKY (vertical) drops off severely on
wavelength shorter than 40M...Study of SLINKY antenna resources indicate
it is resonant around 7.2 Mhz

the last one uses a MiniCircuits 9:1 tranformer that caosts about ~$5.
It has been several years since I bought one.

John Doty is very correct about the advantage of "TV" mathcing
cores over the more common 1" feritte cores. Pluse the TV cores
are cheap and still fairly pentifull.
