This is my take on this highly controversial antenna, the Off-Center-Fed Dipole. THIS IS NOT MY RECOMMENDED CHOICE OF ANTENNA, NOT AT ALL. However there are cases where it is the best possible soluti
A full wave center fed dipole will be voltage fed and have a Z of around 5K ohms and put a vswr on the line of around 10:1. The line loss is negligible because it is a balanced line with an air diel
Great post Rob, great discussion! I'd love to hear more about the practicalities of routing open wire line from feedpoint through heavily wooded lots, through house walls, etc etc, to the shack. 73,

Feeding through house walls is simple Simon. Drill two holes through the wall. Insert a short piece of PVC pipe through each, and seal all on both sides. Insert a bronze screw through each pipe and f

MFJ makes a series of passthroughs that fit under s standard window do you don't need to drill holes in windows or plexiglass. I use one for my long wire antenna (119' sloped over a 70' tree) which I
*It's just a plain old Center Fed Dipole. If I will need a Tuner anyway to cover the Whole Band with an OCFD, we would rather just use the Window Line (450 ohm)... And get rid of all the Coax Losses
I have been following this discussion with a great deal of interest. I have a small lot near the top of a river valley, and the front yard is heavily wooded. This wasn't much of a problem when I just
Wade, if your tuner spits and sputters on 15m, simply add 5 ft. more feedline to it and it will straighten up and fly right. On the coax loss, well unless you're using that cheap Rat Shack stuff, the
It's important to understand that any antenna is better than no antenna and I'm speaking of incremental improvements in terms of an antenna _system_, i.e. the matching network, feedline and antenna,
I might add to that: Choose any equal length for your open dipole which a) suits your local environment at fysical lengths and b) produces the 3D radiation field you need for the required bands Note:
