It's not a given that cutting back the antenna will yield better
reception. You are reducing the aperture.

That sounds like a good rig, but it is going to be more efficient at lower
frequencies. You might rig up another one about 1/4 that length and use it
for higher frequencies.

50 feet=50x3.28=164 meters
300/164=1.8 Mhz which is in medium wave band

12 feet=41 meters
300/42=7.31

6 feet=19.68 meters
300/19.68=15.24 Mhz

While it isn't necessary to have an exact match, down to the millimeter,
getting the length nearly correct is important, because of the signal
strength losses mentioned in the previous post. This is why a longwire is
very useful for very low frequencies. At higher frequencies you get more
noise than signal.

If you try to use a high power transmitter with an antenna badly matched for
the band on which you are transmitting, most of your energy will simply
comes crashing back at your trasmitter and burn up your circuitry s.

Some lucky individuals intersted in very low frequency phenomena have the
space to run wires miles in length, and need special arrangements to
accommodate the incredible voltages generated. Many very strange natural
signals lurk on frequencies that would be voice frequencies if they were
sound, and are very strange indeed.

Hi
I am wondering if I have my longwire set correctly, maybe you could
advise
please.
At the moment I have a sloping long-wire of about 50 foot, going from
the
top of a mast on my house about 35 foot tall to the top of a washing
line
post about 12 foot tall. I have connected the lonwire to my radio by
means
of CB-coax, what I have done is to attach the centre core of the coax to
the
longwire and I have cut the outer sheath on the coax near to the ground
and
connected an earhtwire that is soldered to a cold water main supply pipe
as
an earth.
Only the centre wire on the coax is connected to the actual longwire.

Is there a way I could do better.

I am thinking about getting an active antenna, the Sony AN-1

Would this work better for me or is there a better alternative
available.
I am running an Icom R72
thanks
Rikk

This looks like a good design.

An AN-LP1 wil not do much compared to your current rig.

What are the RF conditions like ; is it a " radio Quiet / Electronics
Quiet"rural area
or are ou in the midst of an urban area..

How did you solder that ground wire to that water pipe?

Hi
I just cleaned the pipe itself with a wire brush till it was shining like
new, got a jubilee clip ( car hose clip) and put the ground wire through the
clip, tightened the clip on the pipe then used my heavy duty solder gun, I
ran a test with my multimeter and it is giving a good ground.
cheers

About four years ago,that married Irish woman in Bognor Regis,England
hired a guy to repair a leaky pipe in their toilet.The guy didn't know
anything at all about doing plumbing repair jobs.He tried to solder that
leaky pipe instead of replacing the leaky pipe with a new pipe.I guess
old Tony bought quite a few pints at the pubs over there with the money
they paid him.

These come in two styles. The zinc (or aluminium?) style is for indoor,
dry locations. The brass version may be buried in the soil. I'd use an
anti oxidant such as Penetrox or NoAlox on the screws and joint if
burying the connection.
