I see no reason ladder line would not work, except if the impedance of the antenna is low as in the case of a vertical (25-35 ohms), the impedance swings on the line will be high, making line length

I think one of things a stagger does is to not only phase the beverages but phase the vertical feeds to also null their pick-up in a given direction. I think JI phases some of his beverages to get ri

The Orion I measured was 13 db better than FT1000 and 25 db better than a Pro11 whan it came to high signal overload. These levels are very high and the difference would probabily not be noticed unle

I believe the length of the feed should be included. I am not personally convinced that there is really a "cone of silence", but why not use these lengths in case there is such a beast. My impression

adjust signals determine I believe the pick-up in the vertical feeds is understated rather than overstated. This summer I experimented with a 580 foot beverage. The signals off the side were only dow
