I live in an apartment with a metal rail patio very similar to the attached photo. I want to put a Diamond X30A on the patio but the radials will be about a foot below the top rail. Will this work, or an I better of with a simple 1/4 wave? [![enter image description here](https://i.stack.imgur.com/3BIK7.jpg)](https://i.stack.imgur.com/3BIK7.jpg)
