I know in the semiconductor industry most of the price increases went into affect as soon as the tarrifs were announced.

The length of the wire will be way way to
long for an antenna this close to the ground.
You are talking about an antenna
formula for a wire "in space".  If the ends of the
antenna are close  to the grown,
and the feed point that close to the ground (You didn't
specify), You may end up having to
double up the ends of the antenna by 3 to 8 feet
on each end.

The way I read it (which I could be
wrong) your antenna will be very close to the ground,
and the ends only a few feet at the
most.

These type antennas are called NVIS
antennas.  For a dipole NVIS this close to the
ground, the standard formula is way way
off.  Ground interaction is a huge factor
on the length of this antenna.

A friend of mine and I played with one
of these,  On his, he ended up with an
antenna around 23 to 25 feet on each
side to resonate on 40 meters. (CAn't remember
the exact length)

We used a 2 8 foot green poles for
support, and two stakes for the wires.

Sorry if I misread your message wrong.

AH18100SR);Some
stakes about one inch-and-a-quarter
diameter;Roll
of electric tape.
Measure
33 feet from one end, split the
conductors apart to make a
dipole, use the other 66 foot length
as a feed line. (Might
need to be closer to 56 feet because
of velocity
factor).
Sharpen
the stakes, push them in the ground,
extend the poles n slip
over the stakes, tape dipole to the
top of the poles. The
end should be about 50 ohms, connect
to coax and
operate.

Re: Antenna analyzer/SWR meter

Frank Artieta
 

Hello :) 
I am very happy things are working out in respect being able to check the swr on the antenna !
To be quite honest !
I find that to be asked the question !
How do I check the SWR on a antenna , I just built ?

Is to me quite a difficult and I think impossible question !

When I install a antenna !
I feel in effect I am really setting up a whole new station !
I have to get the antenna where I want it to be , before I could even do any SWR testing that might be of any value !
I mostly use a dip meter as a antenna creating tool !
A will quit what I am sure some will think as babbling here !
For what I know I am quite sure my antennas are in fact SWR making machines !
I am sure if I could measure SWR at different places along my feedline I would find very large amounts !
Especially since I run my antenna on every band from 80 to 10 meters
I am sure SWR does not bother me nearly as much or in the same way as most !
What does matter is coupling my antenna to my rig !

I am not a fan of Auto Tuners !
We should be tuner tuners and not tuner uppers !

Re: Antenna analyzer/SWR meter

Joshua Wood
 

I completely agree.  What I can tell you, is that if you are a bit handy, I had some of these pcbs made: https://www.hamradioworkbench.com/k6bez-antenna-analyzer.html. They work pretty good, but it is just a voltage measurement - you don't get the actual complex analysis that something like the rig expert does.  I'll gladly send you the bare pcb and diodes if you'd like.   Another option is to make one of these: http://www.qsl.net/k5bcq/Kits/Kits.html kit#25.   They're quite a bit more involved (and surface mount), but it's quite a decent analyzer.   Some people have had luck with https://m.banggood.com/Shortwave-Antenna-Analyzer-Meter-Tester-1-60M-Talented-MR100-Talent-QRP-p-1083237.html.  However, I say caveat emptor to that one.   The rig expert is great - but sometimes a bit too pricey for what some of us need it for.   You won't be sorry if you get one, though!

I still take my stand on getting an antenna analyzer. I like the YouKits FG-01 as it not only gives you the SWR but tells you the frequency the antenna is resonant on so you can make adjustments.  Antenna analyzers are not cheap but if you plan on being in this hobby for a few years it will prove to be a great asset to your test gear bag.  I wish I had had one years ago.

But, then again you can put up any wire and get on the air and when conditions are good you will have contacts.  I did that for my first 10 years of hamming.  If you cut your antenna to formula you will probably get out and make contacts even if it is off frequency a bit. It's just knowing how your antenna is resonating helps you to understand you have done all you can to get the signal going in the right direction and with maximum power transfer.  In QRP every milliwatt out the antenna helps.

Enjoy.  And remember, THIS IS A HOBBY!  It doesn't have to be perfect to have fun.  When I was in RC airplanes some of the planes the club members flew were just junk...... BUT they flew and the guys had fun.  Some get their blood pressure up just getting the looks of the plane perfect.  They spent more time building their planes while the rest were flying their "junk".  Who had more fun?  I think they both did.  It IS a hobby!

I like my KX3 but do not use it as it is just TOO DARNED HOT AND MUGGY here in South Mississippi in the summer. Hopefully this fal and winder It will be tolerable to go out on the grounds and use the picnic tables for QRP with the KX3 and a buddipole de W7KFI

Correct, an antenna tuner consist of wire cutter, tape
measure, and a soldering iron if you cut too much.That
said I’m happy to fool my radio (KX3) with the excellent
internal impedance match.I love my KX3 but QRP
isn’t recommended for a beginner, I can tell you from
personal experience.72 John K3JH

Re: Wednesday Evening 40 and 80 meter Nets - Wed, 8/8/18 8:00pm-9:00pm #cal-reminder

John:

The net is tonight, not last night.  4SQRP uses local (central) time in their reminders, not UTC.  So Wednesday evening at 8:00pm (CDT) is Thursday, 0100 UTC.  I know it's confusing when most hams use UTC.  The reminder title says 8:00-9:00pm.  The body of the reminder announces the net time as UTC as well as Central time.

Re: Antenna analyzer/SWR meter

David Wilcox
 

I still take my stand on getting an antenna analyzer. I like the YouKits FG-01 as it not only gives you the SWR but tells you the frequency the antenna is resonant on so you can make adjustments.  Antenna analyzers are not cheap but if you plan on being in this hobby for a few years it will prove to be a great asset to your test gear bag.  I wish I had had one years ago.

But, then again you can put up any wire and get on the air and when conditions are good you will have contacts.  I did that for my first 10 years of hamming.  If you cut your antenna to formula you will probably get out and make contacts even if it is off frequency a bit. It's just knowing how your antenna is resonating helps you to understand you have done all you can to get the signal going in the right direction and with maximum power transfer.  In QRP every milliwatt out the antenna helps.

Enjoy.  And remember, THIS IS A HOBBY!  It doesn't have to be perfect to have fun.  When I was in RC airplanes some of the planes the club members flew were just junk...... BUT they flew and the guys had fun.  Some get their blood pressure up just getting the looks of the plane perfect.  They spent more time building their planes while the rest were flying their "junk".  Who had more fun?  I think they both did.  It IS a hobby!

My two cents worth, and I am sticking to it.  I tend to build more and get in the air only rarely.  But I have fun and it is cheaper than a psychiatrist or a mistress, and it keeps me out of the bars (and my wife always knows where I am).

I just found the original seven articles by Walt, W2DU, nicely collated
into a single PDF and available to all--no ARRL membership required:

http://www.k6mhe.com/files/Reflect_rev1.pdf

All the parts are worth reading and studying. Part 7 deals directly
with the transmatch and is pertinent to this discussion.

I prefer the term transmatch as it most accurately described the job it
is doing, that is providing an impedance match between the radio and the
antenna system.

As I noted earlier, the articles formed the basis of Walt's Reflections
books. I just checked, and Reflections II is still available from CQ:

http://store.cq-amateur-radio.com/shop/reflections-iii/

Besides the paperback version there are CD and combo book/CD versions
available.

Please, with all due respect, Susan, let's not use "fool" or "believe"
when discussing conjugate matching.  The match is real.  The 50 ohm
resistive load presented to the transmitter byt the tuner is real.  You
are correct that nothing changes on the line between the tuner and
antenna--a Wattmeter placed after the tuner will bear this out.  In
fact, you will see the result of the conjugate match as increased
forward power which is the original reflected power added to the
incident forward wave.  Except for line attenuation and the increased
attenuation due to SWR, all power is radiated.

Impedance matching is employed in all parts of a radio.  I've yet to
read a serious text that discusses impedance matching that describes
matching in anything but technical terms or complex numbers to describe
the impedance involved.

An excellent reference on the topic is one of the thee editions of
Reflections by Walt Maxwell, W2DU SK, if they can be found.  Reflections
III was published by CQ Communications several years ago.  I'm unsure if
it is still in print.

Walt wrote a series of articles in the '70s that were printed in QST.
ARRL members should be able to locate them in the QST archive.  Those
articles formed the basis of the Reflections books.  Walt was an
accomplished engineer, yet the books are written "for the rest of us"
and contain a wealth of information.

Rob,
Buy yourself an AA-54 from RigExpert, or some newer
model if there is one.  You will quickly see how useful it
is for almost antenna situations.  I swear by mine, and I've
been doing antenna work (both amateur and professional)
for more than 60 years.
