Re: High Gain and Wide Bandwidth Dipole Antenna.
I have used EZNEC (and ELNEC before that) for a few decades.? It was written by Roy Lewella, W7EL, and for years he sold it at a modest price.? He has now retied, though, and made his latest and

Re: High Gain and Wide Bandwidth Dipole Antenna.
Thanks, Dave, AB7E, for you pointers. I stayed clear of the "high gain" issue as I thought that should be obvious. But, evidently, not so..... Again, thank you. Dave - W?LEV [email protected]>

Re: High Gain and Wide Bandwidth Dipole Antenna.
There is a fundamental dichotomy here in this entire discussion.? While a wide bandwidth dipole may perform adequately for somebody depending upon their criteria, there is no such thing as a high

Re: High Gain and Wide Bandwidth Dipole Antenna.
Yes, EZNEC is an antenna design / evaluation application. Even a 2-wire folded dipole has a nominal feed impedance of 300-ohms and is inappropriate to feed it with 50-ohm coax. Dave - W?LEV

Re: High Gain and Wide Bandwidth Dipole Antenna.
But my EZNEC model shows 1.2 k¦¸ at the feed. That would require a 24:1 broadband transformer plus balun. I don't believe it is useful with 50-ohm coax at all! I sent out the EZNEC analysis earlier
