- After reading several articles both on and off the WEB regarding a center fed antenna, only one article mentioned a recommended length for the feed line. My shack is located on the second floor of a

- Navigate to http://www.dxengineering.com/Products.asp?ID=50&SecID=10&DeptID=9 and click on the tab near the top of the page called "Choosing the Correct Balun". It has information on feedlines and le

- I believe the use of nonresident feed line is a common consideration. Apple with the dipole, I am thinking that your ground system is a good idea, but maybe not fully necessary, as the antenna is ful

- okay, that makes sense to me. But, then why do they use a 4:1 balun for open feeder line? Happy trails and 73. -- Richards - K8JHR -- == == _______________________________________________ ___________

- Using a 4:1 Balun gets you nowhere near 50 ohms if you're coming from 450ohm ladderline (which is not specified in the oroginal post), it gets you closer to 110ohms. What you need is a 9:1 balun to t

- Because open-wire feeder is often used in applications where it is unmatched - for example a doublet. Although the characteristic impedance of the feeder might be 450 Ohms, in these applications the

- Ah yes... another reminder the radio sees the impedance of the entire antenna system, not just of one or two components. Arghh... I really knew that... Shoot. Thanks. /// Richards /// =-== Although t
