TASH Antennas

[KD6VXI]

Looking at http://www.arrl.org/qex/2009/07/feature.pdf while I was checking out biconical antennas for another project above 2 meters.

Anyone tried one of these?  Works worth a damn?

Would be interested, getting ready to take a few painkillers and try stringing up an antenna so I can play this winter.

interesting but looks like they only have a design for 14 mhz and higher.  It reminded me of the so-called Fractal antennas.

If I had a really restricted plot, I'd try it.  Scale it up and tell everyone it's a "modern sculpture".

[Bill, KD0HG]

For the effort, you'll do much better with a random piece of wire and a tuner.

I like it, but it would get very large like any antenna for the lower frequencies.

I was actually thinking of something like that.  It's got BW like a discone, but doesn't stick out like one does... You might could get away with that in front of the ol mobile home in Mesa, Az. (grandparents lived there)....  As you say, it could be a piece of ugly (modern?) art.

Looks like a bunch of quarter waves.  Interesting antenna, though.

Yea paint it pink or aquamarine and you're set!

I sent the TASH PDF to my antenna designer buddy Spence (KW2S), just to tweak him. Nothing gets an antenna designer more riled up than when I send him a "magic device that can double the range of your cellphone". This usually gets a rise.   

"Gave it a quick read. Not one word about efficiency, simulated or measured, despite comments in opening paragraphs.  Smells bad.  People are still fascinated with SWR. Will give it a more careful read soon. "

-Spencer

And Later...

"OK...

Now I am convinced that this is a case of simulation masturbation.

Compromise, as usual.  In order to get a broad banded antenna, you have to give up something else.  Efficiency, simplicity, or

Gain antennas are the same way, Get gain, FB ratio, tight pattern, in exchange for decreased bandwidth and increased mechanical complexity.

When it comes to antennas, the reason there are so many discussions and arguments is because there is NO SINGLE RIGHT ANSWER and frequently the results are highly subjective and anecdotal.  Even guys with Network Analyzers will argue over which parameter is most important to optimize.

You can radiate RF with almost anything and after that everything else is subject to designer preferences.

Maybe they forgot the R.

The R.. Can't be much on that thing.

The next gen of antenna snake oil could be a spool of resistance wire wrapped around a fiberglass rod tough.

That's thing about antennas there is no wrong way Just follow protocol and experiment I like Loops I like Bazookas I like Beverages Have fun build em all an notice the changes..

An experiment with feed lines all is not just Coax feed...there's the real gain...Balance...

AN Fall is upon us and the trees are gona give their leaves up for us to make those masterful shots through the branches. Its Antenna Time Yeaaaa....my favorite time of the year....
