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 ???? -- Caveat Lector wrote in message oups.com... http://www.radioshack.com/product.as...ct%5Fid=20-043 |

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. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

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

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 -- Caveat Lector "Jerry Martes" wrote in message news:xICFd.15610$ig7.2158@trnddc04...

I 've also heard it as: "Give a man a fish...." "Teach a man to fish and he ends up spending his afternoons in a boat drinking beer." I'm okay with either version as they are for different social settings. As to Stryped, I am in tune with you and Jerry in regard to further assistance. To those of you answering with informative posts and good social graces - my hat's off to you. Howard |

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. Jack |
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. wrote in message oups.com... http://www.radioshack.com/product.as...ct%5Fid=20-043 |
