[TowerTalk] Inverted U vs. toploaded short vertical

[zeitler@ibm.net]

Help! I need to decide which configuration to use for 160 meters. I have 46
feet of pushup mast. I can attach this to a 20 foot 4X4 to get the base up
off the ground a foot or so over the roof of my house. I thought of either
adding a capacitance top hat to it of c. 10 feet diameter and adding
variable L in the base to get it to resonate on 160.

Option two is to go with an inverted U antenna. I don't have a second
support to make it an L so when looking at it from the street it would look
like a drooping inverted L, or a inverted U antenna. 46 feet vertical,
around 50 feet drooping horizonal (from the top of the 46 foot mast which is
attached to the 20 foot 4X4, out around 50 feet, and attaching to a 30 foot
pole) and then down from there.

Which would be more efficient?
