You know, one wonders what happens if you swap the Hustler and the
counterpoise? Coax center to a quarter wave piece of wire, shield to a (ugh! I had one once) Hustler not too near the ground. Nothing different probably, but you never know. -- Crazy George Remove N O and S P A M imbedded in return address "'Doc" wrote in message ... Neil, By now, you have probably figured out that the 'Hustler' antenna as a portable isn't exactly the best idea without a very good ground system. But, it will work with a counterpoise. Not well, but it will work. Something in the near 'neighborhood' of a 1/4 wave for the counterpoise's length should make the transmitter 'see' a load it can work into (depending on how that counterpoise is 'laid out'). There are other options for a portable antenna that may work better than an extremely shortened mobile antenna... 'Doc |

![]() And, one other idea !! (found on the bay of "e"), and available elsewhere- a mount for 2 of these (or the hustler, and an Iron Horse, ect) "1/4" wave antenna -- first antenna goes to center of coax, second goes to shield!! makes a dipole, about 15 foot long, and can be mounted to mast (conductive, or plastic, same diff! tho the impedence will be quite low (because of these loaded whips), and the effeciency will be also not the best, at least would be an effective counterpoise!! and, to boot, parts available to build adaptor at rip-off shack!! got whole thing off epay for about 50 bux, + shipping!!

BTW that is Both Antennas, and the adaptor- not too expensive- cheaper when
need only one ant, and the adaptor. "Jim" wrote in message ... And, one other idea !!

It works well enough above 14 MHz, but such an antenna for 75m is a real dog. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Counterpoise is required for most antennas to operate "effeciently" (have
you ever tried to load a 1/4 wave whip (without one)? Makes great dummy load! Dont radiate worth a darn! Needs the full "1/2 wave" to radiate effectively say that as can be done with loading coils, ect to shorten the effective length, or a ground media for the 1/4 part to work against (tho, at vhf there are SOME 1/2 wave , base coupled antennas that need no counter poise-- but then talking 75 meters- 125 foot tower to do that!!

Oh, and BTW, never stated it would be the "Best" antenna, But, surely would
be easier to pack, and set up, then packing a roll of wire , aprox. 67 feet long, and haveing to retrieve it later!! and, would be willing to bet, even as lousey is this is, would beat that one manufactured by a certain outfit that is about 3 foot high, and LOADS up your coax (ISO-T) to avoid lawsuits, like they involved 73 in years ago .
