About 30 years ago, "73", a ham radio magazine, ran sevveral articles
on
a DDRD or DRRD, or something very similar antenna. The antenna was
amde from 1.5" muffler pipe formed into a circle with a piece notched
out. The antenna
had a farily narrow BW, so a different on was required for each ham
band.
They could be nested one loop inside the other. The follwup letters
rated
the antenna from very good to bad. I suspect I have the name wrong
because
a Google came up with nothing.
Anyone remember the real name of this antenna?



Close. DDRR. It's in the ARRL Antenna Book 1988 edition in the
"Antennas for Limited Space". There's a reference to the July 1972 QST.
They need a great ground, though. Something that the tuned "Hart" loops
like those sold by AEA and (I gather) MFJ don't need. (They're also in
that book in the "Loop Antenna"'s chapter).

But like many hams today, he faces growing pressure to choose between his
hobby or his home.

As the nation grows more urbanized and more housing developments write
no-antenna rules into their deeds, many southern Florida hams find
themselves squeezed out of their communities or pushed off the air.

"Hams are finding that communities are less friendly," said Stephanie
Phillips, a Brevard County, Fla., ham operator and a Florida spokeswoman for
the Amateur Radio Relay League, or ARRL.


Maybe the various radio users (ham, SWL, CB) need to come up with the
equivalent to the red marked towns on the AAA maps. Some source of
information that tells the various emergency radio users that the local
cops don't like mobile scanners, the city is in the pocket of the power
companies BPL program, or the local real estate developers have a love
affair with restrictive convenants. Some map to look at when the place
is going to burn down or blow away and tell the city/state/FEMA officials
that you'll get back to them when it's convenient.

Miami - (KRT) - With pursed lips and a steady hand, WA4YDK spins

the
dial,

much good stuff snipped

I wonder how good magnetic loops are in the context of 2-way HF.
They're certainly one answer for SWL's when space and noise and/or
external antennae are a problem.

I think ingenuity will win in the end.

By the way, Mike; thanks for this article. You may/may not have me
"killfiled" for off-topic posts, but I appreciate a lot of the
information you bring here to RRS.

That goes for many other regulars too. :-)


Mike Terry is clueless. I have him kill filed.

No problem, Telamon. I think he killfiled me, or is just ignoring.
I used to block senders, but later stopped in case I missed something
interesting. Each to his own; I say!

good DX,
