Is This Still a Dipole con't

Use monospaced charctars please.
Feel free to modify the picture to explain your own setup.

For sure you can use a twin-lead 300 Ohm wire going off the balun and then
feeding the antenna wires of different lengths. This 300-Ohm wire works
like a ladder-line -just not a very good one though-.
Best setup is to connct the different wires directly to the BalUn. No
matter if the wires are somewhat in parallel a few feet as the wires
allways will interact some way.
Did you have the 300-Ohm wire split on the far end? This is somewhat
essential to get good signals.



No, it is not split on the ends at all. How much should I split them?
Wouldn't this make more like a limited dipole?

So then just add extra wires directly to the balun and run them out my
window?

Should they be running right along the other lines or should they be in
different planes?


Not having split the the ends of the 300-Ohm wire you just don't have
more than a plain feeding line. To split the wire or to add some extra
"antenna" wires at the end does make it an antenna then. Bowonder you
have "low noise". You simply have "no reception" :-)
Try to put the wires as wide spread as possible. At least in a 90 degree
angle -a 180 degree angle is fine too-. Try different length of wires
and check out what works best for you. You can simply extend a wire with
a nylon cord or a nearly unvisible fishing cord to go to a fastening
point in a tree or a ielephone mast or....
Would you like to tell us what receiver you got?


Volker!!

You and RHF are the men! I hooked up just two 20 ft #22 wires to the balun,
not the ends of the twinlead and wow. Hams galore all over the place that I
never got in good. Now they sound like the next building. It's new beginning
for me.I think I love you. How about a date?? :)

BTW,

the noise floor is still extremely low. The R-75 is a super fantastic
reciever and don't forget it has DSP. With the balun, it's like smooth ice
baby.

If you love me really, make a date for me with your girlfriend ;-))
A ticket to Berlin/ Germany is what she really will appreciate :-))

The 1:4 BalUn is designated to work best with a set of asymmetric
dipols. Extend one of the wires by 30-50 ft if you can. You can use any
(cheap) wire available! You will be blown off your seat then :-)

I only have like 20 ft to work with for the extra wires. What do you
suggest? 8 ft on one, 10 ft on the other??

BTW, you can have my ex wife. If I could get her deported to Germany for
under $1000 I would do it.
