[Lowfer] The culprit....... Who is USA

[Bill Ashlock]

Paul, you old low-down loop pole cat!

>...... about 3 miles from VD.  I know, hard to believe when you look at =
the signal strength difference.

I do!

>The antenna here is a 50X50 Ashlockian loop with a Rusgrovian twist.  In

nits)

That must be inches x inches in order for Dennis to see such a low level =
down there in Swansea by the sea! =20

>The loading capacitance is 6500 PF which seems a little low but who
>knows.

I know - and that's about what the Inn keeper (Mike, lost looper, Staines=
) found for his #12 Power Loop.

>The antenna is made of #12 wire at this time and I will be progressing t=

Just get that #12 humming first, sir. Do you need a test loop having the =
1.3 ohms Rac allowed for a #12 loop? No trouble at all - The elves here h=
ave got the process down to about 10 minutes. <G>

You are correct on this but the loss isn't that great for a loop with a d=
ry Rac of 1.3 ohms - maybe 20% at the most if it's really wet there, but =
I'll be awaiting your numbers.

>There is a mismatch of 3 types of coax feeding the thing, some is 75 Ohm=
s and
>some is 50 Ohms.

Ooooh. You need the final right at the base. The line, even if high quali=
ty, can be tricky to match though the step-down xfmr.

Well 'USA Today'. Good to see you are finally doing it - having some REAL=
 fun, that is!

Bill
