Hi to everybody. This is my first post.Thanks for having me worldwidedx!!! I'm back into the hobby (I have'nt hamed for 15 years.) I have the bug again!
Years ago a friend of mine helped me put together an antenna. We took a pdl-2 and a moonraker and put them together. It consisted of the quad reflector, the folded dipole driven quad director from the pdl-2 and the rest were a director 1 and director 2 from the moonraker, using the moonraker boom. We called it a Quagi but i know it's a little different.
It seemed to work well with about 1.5 to 1 match.
I have kept all the parts and started cleaning and putting it back together. I have looked on the net and found a program to make it work on 10 meters. I set my target resonant freq. between 27.405 and 28.300 as I am into cw ham and thought if i wanted too, I could use it for 11m sideband if I felt the need.
My first q. is, has anybody done this before and what were the results? I was never able to compare it to a pdl2 or a moonraker and we did'nt have an antenna analyzer or field strength to see how it was doing, though it seemed to shoot skip well.
Second q. is, would i do better just making it into a 4 element quad as I have all the stuff? I know the driven element of a quad has more gain then a yagi and avanta claimed that the pdl2 had even more gain then what they claim a quad does because of the driven folded dipole that feeds the quad element. Also from what I have read the quad has more gain then the yagi only because of the driven element but after that stacking directors in front of the two is a wash between them.
Third Q. is, are the two yagi director elements from the moonraker directing just the driven folded dipole or just the driven quad that the folded dipole feeds or both???
Last is, we used the two yagi directors just like the moonraker, they mount directly to the boom. In my application now with the pdl2 driven element should they be isolated from the boom?
Any info would be much appreciated and I would bow to your superior knowledge...please help! I have spent several days trying to answer these questions by researching the net, my results were a headache! Thanks in advanced,Darryl , kc7max
