But I am not an electrical guy, but more a mechanical one.

It just needs to be there. The majority of which was THHN or some equivalent. I think the reason is that the antenna gets electrically shorter as the frequency goes up and is blocked more by the surroundings. On the other hand, the portion above the traps is a bit different

The most noticeable changes were that A dropped to 11 from 22, and K from 3 to 2 over the course of roughly 5 hours. Please upgrade your browser from current version Microsoft Internet Explorer - I have it ground mounted with about 25 radials under it. The loop does not have to be any particular shape. Quadrature hybrid directional couplers Fisher QST I refurb'ed it into almost new shape.
Used car battery cable to run ground from the plate to the antenna mount base. Now I earlier mentioned that shielding the CG improves tuning efficiency. These antennas perform well in restricted space areas. I used a shovel to make a slit for the coax. There are no magic antennae. The soil here is clay and apparently pretty full of water which I suppose is more likely in a wooded area. Strength is irrelevant, but conductivity is.
Assembly is easier if the tubing sections are pre-marked. The soil here is clay and apparently pretty full of water which I suppose is more likely in a wooded area. If space is limited, some compromise is permissible providing the droop angle is held between degrees below horizontal with radials fanned out as much as possible. Installation of this product near power lines is dangerous. Digging a suitable trench, snaking the coax through a tube and burying it would have been a much bigger task. This setup allows me to tie all my radials and feed line shields to the tubing, it is rigid and will last many years.
