[IRCA] More EWE questions
Hello IRCA'ers Can anyone tell me if it would be of benefit to increase the height of the upright poles from 10 feet to 12 feet. 12 feet would be the maximum "her indoors" would allow hi! What, if any, would be the advantage?

Re: [IRCA] More EWE questions
Barry, "More wire, higher" is usually better, but it may be hard to tell the difference between an existing 10' height and 12'. I would go with as much height as I could string up, however, and would not chose 10' over 12' unless limited by physical restrictions. In picking up weak signals, there are so many other factors involved that there would be no way to tell if the signal you heard on the 12' antenna system could not have been heard on the 10' system unless both were operable at the same time for comparison. 73 Gil ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
Re: [IRCA] More EWE questions
Both of my EWEs are better than 20 feet in height and moving them from 18 feet to 22-25 feet did make a difference. I wish I had the trees to make them 50 feet in height. 73, Patrick Patrick Martin KGED QSL Manager ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
Re: [IRCA] More EWE questions
Barry, Think of your EWE as the upper half of a loop antenna... the other half is reflected in the ground. If you raise your EWE from 10' to 12' that is really adding 4 feet to its total height. The gain of a loop is directly proportional to its area. In the ham world, its somewhat controversial whether a EWE really acts like half-a-loop, but I've proved it with rather careful experimentation So, figure your loop area both ways and that percent change in area is, proportionally, about how much more gain you will have.

Re: [IRCA] More EWE questions
Barry, This "gain" stuff may be old hat to you, but here is what a buddy wrote about gain and interpreting decibels. It's at the bottom of the article: http://bellsouthpwp2.net/w/u/wuggy/testing.htm I'm also sending you and John by email a pdf of the original article on the EWE by the inventor. If anyone else wants it, drop me note. 73 Gil ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
