Are you sure that there is pseudo-Brewster enhancement over fresh water? John KK9A There should be less field cancellation at very low angles for a vertical that looks out over fresh water... look up

I doubt that steel price is correct. After shipping you will still need galvanizing. Depending on your antenna load you may be able to use an aluminum mast which needs no corrosion treatment and you

Tower top plates and rotator plates are not manufactured very precisely and trying to line up two bearings plus your rotator bearing could be difficult. If it's not lined up exactly it will cause som

You should fill the hole with concrete, what else would you put in it? One yard is not a lot, but I'm not sure what the minimum concrete delivery is in your area. Another other option is to buy 40+ b

A model will give you an accurate SWR curve for any height and would provide the best answer to your question. I think 15' is too low for adjusting, I would pull it up to 35 - 40' high which should g

468 / Frequency (MHz) should get you close, however your tower is really too short for a sloper. Why not just put up and inverted V? You can use your TX SWR meter to tune the antenna. Adding a beam l
