- I'm using an Autek RF-1 to attempt to measure ballpark impedance at the antenna feed point. The antenna is a coil loaded (50' level) 75' vertical, with 34 radials. I read 116 ohms, which I question!

- Hi Tony..... If you can only do one, I'd take the easiest method to install. But, if you can do either, why not do both? John W4II _______________________________________________ ____________________

- Roger..... As you know, an inverted vee for a given freq is a balanced antenna with essentially equal current and voltage on both legs. Grounding one leg at or near the feedpoint will destroy that ba

- Anyone have real-world experience with phased verticals on 40m? Actual comparisons to high dipole, etc would be greatly appreciated. Bottom line...was it worth the effort? 73 John W4II ______________

- Jim.... I noted the "simple" vertical half-wave dipole configuration on your site. Is this the type used in your test? Also, do you feel the choking is sufficient to "eliminate" the rest of the feed-
