As someone with personal experience regarding her nastiness and intolerance, I say good riddance. She sucks as a human being.
Judgmental much?

She's a terrible person and I don't have a problem saying it. I also don't have a problem with you judging me over an opinion. Maybe look in the mirror?
Walk the talk.
By my count, you have two strikes:
1. Being very impolite, and
2. Not knowing what the concept of libel entails.

Anything else you’d like to add?

You're a riot. I bet you're real fun at parties.
So now it’s at least 2 people you don’t know but unhesitant to  make uninformed judgments about. Perfect record!

I like the loop.  And fed with window line and a tuner makes a great multiband antenna.  It does not have to be cut to frequency, but bigger is better up to a point.  There are better smaller antennas for VHF/UHF.

I saw the video. It would have been funny, but it hit a little too close to the truth. And nothing about her leaving ARRL.

From what I gathered via Google searches, she got in trouble for writing a  license tracing manual, and entering into a contract for its publication, without obtaining prior approval from the league. ARRL cut her loose for what they perceived as a conflict of interest violation. IMHO, she should have gotten approval in writing first.

I saw another supposed cell phone chat screen capture where she was suggesting a person perform a sexual act on Donald Trump. I don’t know the circumstances, or if it was true, but she should check her political opinions at her residence door (and perhaps the voting booth).

Like it or not, once you take a position with an organization like that, you are no longer a private citizen. And that includes publicly denigrating members of one or the other political party, as it calls into question her ability to serve all members of the ARRL. If she wants to exercise her free speech rights, she can do it from her own pulpit, not the league’s.

And Trump is an idiot, but Hillary was a witch. Both pills are poison for a director.

Gotta budget??
A simple vertical dipole will do, or a  60 ft tower and 6 element beam might work also.  There is a cost difference though.  Can it be directional?
A vertical extended double zepp is non directional and has gain... and is not too large.

How long a coax run?

Did anyone bother to watch the video before spewing their venom?

Quote from: US7IGN

Why hasn't anyone proposed a delta loop on a fishing rod yet?



It isn't expensive enough to be that good?

Because some people don't think beyond commercial
antennas and their marketing claims?

Full wave loops can be great antennas, and can be
installed in many different configurations.  The shape
can be modified to match various impedances, from
less than 50 ohms to almost 300 ohms.

But while a traditional loop has a little bit of gain over
a dipole in free space, over practical ground the situation
gets complicated quickly.  For a horizontally polarized
loop, a dipole or inverted vee hanging off the same
support may give a bit more gain at low angles, because
the average height of the antenna is greater.  (The
bottom wire of the loop, being at a lower height,
doesn't contribute as much low angle radiation.)

For vertical polarization (which is what I presume your
loop is attempting to achieve by feeding it in a bottom
corner), performance is greatly dependent on the local
ground conditions.  They are great over salt water, and
should work pretty well in much of the Midwest where
soils tend to have high conductivity.  Here in Oregon,
where most of our soils are volcanic with poor
conductivity, vertical polarization at low heights doesn't
work as well.

But there is another factor that has been touched on:
what distance the antenna is intended to cover.
For really local coverage (out to 30 km / 20 miles or so),
height is more important, as the propagation is usually
via a direct wave, as is typical on VHF.  This a low vertical
isn't going to work as well.  In that case, you would want
a taller fishing pole.  But for ionospheric propagation, that
isn't as much of an issue, and the low vertically polarized
loop can work quite well.

@ KG4RL - I saw that wallwarttamer ... I would build my own supply before paying $20 + shipping to build a fix for a wallwart... wouldn't you?

@ Mark N7EKU - Yes, I ran the test again and the scope was set to 10 ms/div. I agree that seems weird. I tried several different wallwarts and got different forms of noise (some which looked like high frequency ringing) but all of them (except one) had significant levels of noise that could be heard in my device. My current junkbox is limited, but I did try a few toroids as chokes with no luck... this is an area I want to pursue further as I don't have much experience working with them. Also, my scope (and skill level) isn't the best.

@ WB6BYU - yea, filtering out such low frequencies is kinda like building a speaker crossover with those huge coils!

@ VK6HP - thanks for that circuit on the simple capacitance multiplier and the link! I looked that over and will try it sometime when I have more time to experiment.

Just for context, my bench supply worked fine in this application with no noise passing through to my device. And I did finally find one wallwart that works OK with almost no ripple and does not cause issues with my device- it's rated for 3A and I guess is just better made.

Thanks to everyone for your time and input! I need to study common mode chokes, and not rely on wallwarts so much ...
