Default Are these antennas any good for both transmit and receive?

Come on now help yourself a little bit -- the URL you gave has the answer
when you click on "Features"

It sez

Your radio shack discone antenna receives VHF and UHF frequencies between 25
MHz and 1300 MHz
(1.3 GHz), and transmits effectively at 50, 144, 220, 440, 900, and 1296
MHz. It handles a maximum transmitting output power of 200 watts and
provides a standing wave ratio (SWR) efficiency of 1.5:1 or better over
the receiving/transmitting spectrum.

Now why can I find that and not you ???

Are you putting us on here ????

The information as posted on the Web site is only part of the answer.
Heck, a good high-wattage dummy load would have a better bandwidth and
SWR than the discone, and yet it'd make a (somewhat) worse antenna.

As to the original question, is a discone "any good for both transmit
and receive?". I'd say the answer is "Yes, they're 'any good' but
they are not 'very good'."

They're compromise antennas - fairly wide bandwidth, acceptable SWR,
but a radiation pattern aimed at the sky or the ground (depending on
how you mount them) rather than out at the horizon. They're a decent
choice if you can only mount a single antenna, need to operate over a
wide range of frequencies, and don't need to be concerned about
weak-signal operations. My city ARES/RACES group uses them for
pre-sited emergency antennas at the city fire stations, community
centers, schools, and other such locations... plug an HT onto the end
of the drop cable and you're on the air. The results are quite
acceptable for working nearby repeaters, simplex to the city EOC,
and so forth.

They're a mediocre choice for serious single- or multi-band operation,
though.

The answer you gave was given to the question box several times in past
postings

He just keeps repeating the questions over and over

I for one give up trying to help him

Stryped is kinda hard for me to figure out. He does seem to ask alot of
questions that could be easily answered by researching some basics. One
thing interesting is that he has gone to other news groups asking antenna
questions to metal workers. Yet he has no time/ability to search for
answerd with Google. I too have decided to "give up trying". I could
surely change my decision if he showed some effort to learn the normal way,
read/research, or just *do* something.

Agree Jerry reminds of an old adage

Give a man (person) a fish and he will be back the next day for another
(maybe 3 times a day - huh)

Teach a man to fish and he gains his respect and yours

We tried

Case closed

That does not tell me if it is a "good" transmitt antenna compared to
other types. (Ground plane, j pole, etc.)

I can't believe anyone is still taking the guy seriously since the first few
rounds. I wrote him off a long time ago when it was apparent he has heard of
everything, understands nothing, and refuses to look up anything, no matter
how simple.

You will prbably get a bunch of "don't buy Radio Shack junk" posts but I
have had one up and working fine for about ten years.

Try the Radio Shack on 1134 W 9th St. or simply call them at 726-3099
