There really are two separate considerations:

?

1.? Will it "match"?

?

2.? How efficiently is that length of wire RADIATING (or receiving)?the signal on that frequency?

?

I've seen 37 feet listed as a length that would match most - but NOT all - of the bands.? I'd expect radiation efficiency of the 37 foot wire to be very poor on the lower bands, however.

?

It's also going to depend upon your installation and antenna configuration.? Grounding and "RF in the shack" issues are critical.

?

I'd start with the 100 feet, see what that will match and start trimming until I was satisfied.

??

Keep records and share?your results with the group.? Please include the wire size (guage), type, and configuration of your antenna (slopper, inverted L, etc).??

"Zip" cord wire?is an inexpensive way to?experiment with wire lengths and antenna configurations.

So what is a good wire lenght that will cover all bands? I have up to
100 feet of wire to work with. looking for 160 to 6 meters but 80 to
160 would be fine.

Gidday all,
I have uploaded some photos of my mobile setup.

It may not be 100% conforming with pure antenna theory, but it works!

Regards,
Peter, VK4TGV.

Sure can, I use a 1:1 balun with about 100mm of wire connecting the
ground and antenna terminals to the balun, then run about 2 metres
of co-ax to a spring base with a helically wound HF whip mounted on
it.

Tunes everything except for 160m (not suprising), to use low band I
use another piece of wire connected to the top of the whip and with
the other end chucked up into a nearby tree. Bit hard to do mobile
though ;-).

It is probably better to use a 4:1 in theory, but I thought it would
not matter so much with such a short balanced line, and it turned
out to be true.

I had promised to take a few photos, I must get around to it.

Hey all,

I sold my truck with the 102 inch whip....I had the fc-40 about 3
inchis away from the inside lug of the ball mount so it was

perfect

for 10 gauge wire from the fc-40 lugs to the ant.

Now I cannot drill into my (new) Olds Bravada, so I need to figure
another way.

Can I cut off the end of a 15ft coax, wire it to the tuner and
connect the other end to a pl259 mount for the whip, off the

bumper

sor something?

Didn't think I could use a coax.

Also, what if I used a 4:1 balun in reverse to accept the wires

from

the tuner and adapt them to the coax to make the run over to the
whip?

Can a balun be used in reverse? Could use it in my shack to

attach

attick mounted slinky to the tuner.

Just a dumb general.

yes, I just conected the loop to the two connectors. I asked Yaesu
about using the tuner on balanced and unbalanced lines and they said
it should be fine. It worked well except for the QSB which I believe
came from excessive SWR.

One other question: Jon, how did you terminate the loop? Just

connect

it to the ground terminal of the FC-40, or what? Yes, I'm a newbbie

only about 10-15m high. I was using a sling to string the wires up
in the trees so I couldn't get too high. I also used about 25m of
counterpoise running on the ground.

I was able to get tuned fairly well on 20m and most of the time on
40m. 80m was generally a problem with the tuner as I got HSWR most
of the time. I didn't think 33m was close enough to 1/2? (40m)

for

it to be a match problem on 80m.

Does anyone know the range of impedences that the FC-40 can match?

Another thing that I noticed is that on 80m my carrier would have
practically little SWR but my voice modulation (LSB) would peak the
SWR.

I also had some complaints while QSOing across the Atlantic about
QSB. This may be the becuase of the FT-857D sutting down due to

HSWR

peaks.

I also tried using the FC-40 with a 5x10m vertical loop 2m off the
ground. This had the same tuning characteristics.

Jon & The Group:

There are about five FC-40 reviews on eham.net so far, some of them
dealing with wire length(s), and impedence the FC-40 did/did not
match (info that is sadly missing from the Yaesu brochure AND
manual). The reviews can be found at


As always, based upon your individual installation, you may find
differences.

Looks like an antenna analizer would be a good addition to the kit,
at least long enough to do some experimenting.

One other question: Jon, how did you terminate the loop? Just connect
it to the ground terminal of the FC-40, or what? Yes, I'm a newbbie

As with any antenna, Just try it. Let us know what happens. Oh, use
low power to start.

I'm constantly in a state of confusion. ;-)

Is it better to use a varable length antenna system, like a
Screwdriver, than to use a random length wire/tuner coupler?

I use an ATAS-120 with my FT-857D in my truck and am really happy with it. I know there are better screwdriver antennas but the ATAS-120 is simple to install, and works right off the bat. Press the "tune" button wait a few seconds, and you're ready to transmit. It is cheaper than any other screwdrivers I've found, especially when you add in adapters to be able to tune from the "tune" button. It fits under the parking garage at work, and I've made a lot of 17M SSB DX & 40M SSB contacts with it. I've ordered a tuner for my FT-817 so that I can change or build antennas to suit my needs. I've never been all that interested in building antennas until about 6 months ago. Now I can't seem to quit experimenting. A tuner is more versatile than a screwdriver, and from the demonstrations I've seen, a tuner can be faster. So "better" depends upon your needs.

I have a FT857D, I've passed the General written exam, & have about
got the code...(Yes, I know that it's been proposed dropping the code
requirement, & Yes, I still want to learn it.) I'm about ready to
start seriously building or buying my HF antenna(s), I'd like to
start on the right foot.

Great. I upgraded my ticket to General in April. The 5 wpm exam is not impossible as some would like you to believe. I have a website I put together (nothing fancy) to explain what I did to learn the code. After I upgraded I had several requests for help. You can check it out at: I was really proud of myself for passing the code exam...I knew eventually the code exam would be dropped, but wanted to pass code instead of being handed HF privileges. Some would say that 5wpm=handed. Somewhere along the way I started enjoying copying code. Although I've not used it on HF yet I hope to start soon.

Even if they dropped the code exam a few months after I passed the exam I still will have the satisfaction of having passed. I know several Technicians who told me I should have just waited instead of putting myself through the torture of learning code. (One has been waiting for 2 years now. He bought a brand new FT-100 a couple of years ago) But I'm having a ball on HF! And they love hearing that I worked Nicaragua and Costa Rica and that I worked Maine on 2.5 watts & California on 5 watts last week.

Good luck passing the exam!

I'm pretty new at this, been reading up what I can about tuners &
stuff. I'm also a bit overwelmed by all the advertising about this
tuner, that tuner, and I'm a little confused...

Is there a difference between a "Tuner" and a "Coupler" or do the
terms meaning the same thing?

Does a tuner or coupler tune a wire into resonance? Or does a tuner
or coupler match impedence?

Is using a tuner or coupler merely "presenting" a radio a low SWR
even when it is working into a mismatch?

Can a tuner or coupler make a less than optimum antenna more
efficient; can it increase gain?

Is it better to use a varable length antenna system, like a
Screwdriver, than to use a random length wire/tuner coupler?

I have a FT857D, I've passed the General written exam, & have about
got the code...(Yes, I know that it's been proposed dropping the code
requirement, & Yes, I still want to learn it.) I'm about ready to
start seriously building or buying my HF antenna(s), I'd like to
start on the right foot.

These questions I've stated will go along way toward the decisions I
may make.

Inquireing minds want to know...

Thanks in advance for any inputs that may come...

I GOT MY FC-20 WHEN I PURCHASED MY FT-847 AND IT HAS WORKED WELL ALL
OF THE TIME. IT, OR THE FT847 DOES HAVE A COUPLE OF QUIRKS. IF I
SHUT OFF/DISABLE THE TUNER WITH THE TUNE BUTTON ON THE 847 AND SWITCH
BANDS FOR EXAMPLE 20M TO 17M, THEN TURN ON THE TUNE BUTTON THE TUNER
TRIES TO TUNE AND THE TUNER ICON GOES AWAY. IF I TRY TO XMIT ON THE
NEW BAND I GET HISWR INDICATION ON THE FT-847. I THEN GO TO 10M, HIT
THE TUNE BUTTON, THE TUNER TUNES AND THE TUNE ICON STAYS ON. AS LONG
AS I DON'T HIT THE TUNE BUTTON AGAIN, I CAN SWITCH BANDS AND THE
TUNER TUNES AUTOMATICALY AS IT SHOULD. DOES THIS HAPPEN ON OTHER
YEASU TUNERS OR IS IT JUST MINE? IT ONLY SEEMS TO CORRECT ITSELF
WHEN I TUNE ON THE 10M BAND.
ALSO HAS ANYONE FIGURED OUT A WAY TO USE THE FC-20 AND CAT CONTROL AT
THE SAME TIME?
