Agree, its a full wl OCF, fed @ about the 1/6 wl point. The 140 degree angle allows it to develop some gain in the off end direction. The diagram shows a feedpoint of 50 Ohms, so (if) coax fed, it must be a monoband antenna. Mounted that low, I don't see how it can not be a cloudwarmer.

The original article was written in Russian, and the translation made some errors. This antenna cannot have circular radiation. Another translation states "the antenna thus configured has a substantial vertical component with a radiation pattern in a vertical plane."

As usual, the Zeddites are complaining about spectral purity.

It's a DRM Digital Radio Mondiale signal. https://www.sigidwiki.com/wiki/Digital_Radio_Mondiale_(DRM) click on the AUDIO SAMPLE arrow and listen The Chinese dragon is an AM signal playing music https://www.sigidwiki.com/wiki/Chinese_Firedrake_Jammer

If that were really correct, you wouldn't be worrying about a "1:1 match". Hint: see post $37

I may be wrong, but,...... I don't think he will do much listening to 30 meters. YMMV

Gee, I dunno. KFM is a mental case, but, I have never heard HIM threaten children, ....and for a few years I had a rig parked on .313 and before that, on .274. Bear in mind, that a LOT of the things he is blamed for are actually the result of very good audio editing by a certain Amateur living...

Dayum, He's pretty close to VE7KFM, but, I have never heard Karl mention children.

The new (full retail) price on that rig was $13,000 USD.

Actually , what he probably did, was to switch in and out an electrical 1/4 wave length in the feed line between 2 of the antennas. That will change the radiated pattern from a figure 8 @ 90 degrees to the antennas to a cardioid pattern.

RF is AC

DAYUM,.......... Perhaps there is a reason that an added RF choke on those A99's/IMAX's works better when located about 1/4 wl below the feedpoint;)

No He didn't,.. We can kick this around for a few pages.

Take a look at the MFJ 1234 rig pi........... less than $300... works with just about any radio/ phone/operating system/ect https://www.gigaparts.com/mfj-1234-rigpi-station-server.html

You will get a lot of strange looks from the cashier if you buy a gallon at a drug store,..... and pay waaaaaay to much. Walgreens 16 oz for $6.00.. about$45/gal Get it from an Ag. type store like Tractor Supply,...... its a lot cheaper ($20.00/gal) and they sell it by the gallon all the time.

Now thats funny,............... and correct on both interpretations.

I learned to spell HAM with all capital letters in this thread.

What many people miss, is that the vehicles body itself is one plate of a cap....mounted on 4 rubber insulators, the other plate is the actual earth directly below the vehicle. .. and my mobile (NOT a mag mount) has the feedline choked off with a ferrite right at the feedpoint, outside the...

What left overs?..............

if that (the coupling) was effective, then why did you get an RF burn from the mic? All mag mounts use the shield as part of the antenna. that shield length is calculated into the design. Turning the amp on did not create a new problem, it was already there after you cut the coax but you...
