-ps- I like AM/MW Loop Antennas made with Litz Wire.

Yeah, you post so much garbage here I wish you could do the same.

My Loop $0.02

I have a homebrew broadcast band loop that is 33" on each side. *It is
9 turns spaced about 1/2" apart. *I ring it with a 900uuf variable. *I
had built it with *#16 solid wire but changed it to 165 strand of I
think it was #42 or #46 litz.

I could not tell the difference between the litz and the solid magnet
wire - they worked about the same. *I can pick out signals that are
totally buried in the noise with either wire. I have a seperate
winding that is about 10" in diameter that I use to drive the hi
impedance input of my receiver. *The only benifit of the litz wire
that I can tell you is it looks pretty. *My loop was built with retro
look and the litz looks nice. *I park it in the living room, so the
wife was glad when I got rid of the gnarly kinked up magnet wire. *I
think I paid about 40 bucks to make my loop look nicer. *I will concur
with Mr Telamon- Save your money. *And to answer your question - you
should do just as well with homebrew as with store bought with same
dimensions. *And size does matter. *If some guy tells you it dont, you
can be sure he is playing with a small loop.

My friend just built the 20db preamp for one of his 160m & 75m loops
and told me it does a nice job. *It is in Jan/Feb 2001 QEX. *By Zack
Lau, W1VT.

Thanks for the thread. *Let us know of your adventurers with your
loop.

Bob N9NEO,

Yes the Litz Wire made of 165 Strands of *#42 to
#46 Wire is good stuff and pricy too.

For One and All,

Anyone Remember an AM/MW Loop Antenna -webpage-
Using Twin Lead as a Coupling Coil and Feed-in-Line ?

- FO&A,
-
- Somewhere at some time I came across a webpage
- that featured an AM/MW Loop Antenna which used
- a short piece of 300 Ohm TV type Twin Lead as the
- Coupling Coil between the Loop and the Radio.
-
- One of the Wires in the Twin Lead was connected
- across the ends or the Larger Loop and the Tuning
- Capacitor.
-
- The 'other' of the Wires in the Twin Lead was then
- connected to another piece of Twin Lead; that was
- used as the Balance HI-Z feed-in-line.
-
- IIRC - The reason this was done was that the Receiver
- was already using the SO-238 Jack for the External
- Shortwave Antenna and this Twin Lead Coupling
- Loop Arrangement allowed the use of the Receiver's
- HI-Z Terminals with out having to use an External
- Antenna Switch with the two Antennas. *Just use
- the Receiver's built-in Antenna Switch to change
- Antennas and go from Shortwave Listening (SWL)
- to AM/MW Radio Program DXing (BCL).
-
- Anyone remember a AM/MW Loop Antenna webpage
- using Twin Lead as a Coupling ? - I have looked and
- looked but can't find it again. *Maybe it has been
- removed ? - i want to know ~ RHF
- *.
