Think about it this way If you are in the dark in your back yardand you shine a high powerful flashlight at the forest you willlight up the forest, but if you shine a little penlight at thesame forest you won't see much, and with that said if you standon a ladder and shine the penlight down you can then go justa little farther because of height and then you can concentratethe beam on objects and yes get out farther, but still only so far.
This is exactly what we are doing here, so think about a 5-watt CBit travels to the next town because of the line of site, because it has just enough wattage to make it by the line of sight...Most cb'ers want tall towers and never would put their antennas on the ground use a milliwatt and say yep that's a great idea... (SAID NO ONE EVER).Now let's use a milliwatt CB and try to talk to the same townand they will not hear you because that milliwatt transmitter will not bounce off the atmosphereit won't get to the next town and its restricted so much onlyline of site and height allow it to reach farther until diminishing returns like the penlight on top the latterit can only go so far...
You can build a reflector for your antenna or a radial field etc but in the end, height always makes might and using milliwatts you want to be up in the air free of trees buildings and objects that absorb your milliwatt and waste it, Try 30-40-50ft and see if your not twice as far as you were at ground or at 10ft etc.
The key is to stay away from objects esp houses, roofs, buildings, trees, and get up into free space and don't ground it rather instead use the audio line and the voltage lines to the transmitter as your safety ground here's a device I use which each line + - Audio in etc has a terminal grounded so if static or God forbid you take a nearby strike etc this will dissipate before it enters the studio.

safety ground for data utility cables for lightning protection...
All i am saying is we have been doing it wrong for a long time and need to rethink this whole idea. we are not mega stations using mega efficient antennas we are microwatt peanut whistles and our only true friend is the line of sight... Let me know your thoughts.
