Hi Crazy and all,
Jumping the gun or putting the cart before the horse you are. Antenna design, performance and propagation are sciences in themslves, I suggest you do your study homework before asking questions. When you have a bit of knowledge under your hat you'll be in a position to ask more intellegent questions about specific subjects. Right now you're just trolling for answers, I see confusion on the horizon.
By the time you're through you'll have a place that looks like the home of a copper spider that's never done. You'll try this and that based on a specific set of GOALS, no two alike because no two antennas and no two sets of conditions are alike. The long and the short of it is there are many bows and many arrows, you have to know what to use to hit any given target and then you have to be an archer. You'll never be an archer by asking questions, you have to STUDY before you can choose your weapon.
Just a muse, "I shoot an arrow in the air, where it lands I know not where." Well, an archer knows exactly where it landed, right where he wanted. A signal is like an arrow, wave propagation follows similar principles. Shoot high and it falls down and short, shoot low and it falls flat and long. Radio waves do the same, it's all in the vertical takeoff angle. Are you getting the picture? You choose the antenna for the job, the signal will come to land where you want it.
When you're ready to ask questions remember to ask the right questions to get the right answers. When you have a sufficient knowledge base you'll know which questions to ask. For now try this one, "Where do I get these study materials?" and you're off to a good start.
Dave, please bear with me a moment.
"I something at todays meeting of my local Ham group that is do not bury the feedline coax untless you have the type can be buried."
Even with a few words missing I get the idea, burial may result in cremation. While I'm in the mood for poking fun, you reminded me of how I used to tell CBers how to cut through the skip interference and work the ground wave, bury the antenna. Oh, ladder line is better than coax for transmitting because the signal finds it easier to climb up to the antenna. On the other hand coax is better for receiving, it slides right down and doesn't go bumpety bumpety bump on all those spacers. (;->)
