OK, I've seen the responses that the G5RV ,and especially the Jr. variety,
are below average performers. And that a center fed doublet with open line or at least something like 450 ohm ladder line is a better option as long as you have a balanced to unbalanced external tuner. I certainly won't argue that, but suppose I want to be able to use my Kenwood TS450sat's internal tuner (unbalanced input only), what are my options for a decent, simple multiband antenna (80/75,40,20,17,etc)? And, I understand that 'fan' dipoles can be effective (I have an Alpha Delta DXEE for 40/20/15/10, it's poor on 40 BTW). I don't have enough tress for multi element dipole anyway. Can a 'doublet' with 450 ohm ladder line to a 4:1 balun then coax to the tuner be effective? What would be 'ideal' dimensions for the doublet? BTW, I did download the 'dipole3' program and my friend with the G5RV Jr. was VERY disappointed to learn that his Jr. wasn't worth a hoot, even though he has had fair success with it. Guess in the end it all comes down to what you have faith in :+)) . Nice little program, thanks for pointing me at it. Fun to consider these things and ALWAYS to experiment. Cecil, I took to heart your 'l-loop' and modified one for 30 meters. I have had GREAT luck with it! Best thing I've tried on 30. Thanks! "Cecil Moore" wrote in message ...

What might be the optimum band for the Jr., if it has one? Antennas are scalable with frequency. The full-sized G5RV is a pretty good performer on 80m, 40m, and 20m (also 12m). The 1/2 sized G5RV will therefore be a pretty good performer on 40m, 20m, and 10m. -- 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! =----- |
