Here's an explanation of what I'm working on.
Frequencies used, are used for a reason, they use 2.4 Ghz for phones and microwaves and wifi, because of the characteristics of that frequency.
A used Frequency is everywhere, and the Dowsing Frequencies, piggyback along with other Frequencies. A distant targets element signature, would ride a used frequency better, than any length antenna.
The 2.4 Ghz frequency 1/4 wave is only 1 1/2 inches long of an antenna.
Way to short for Dowsing rods.
The next best bet in helicoil, or loop or bowtie antenna design would be, the longest length low frequency I can incorporate into a well balanced Dowsing rod antenna.
I haven't got a set of Helicoil Dowsing rods, If I make a set, I want it to work, and for that, the length has to match an active 1/4 wave Mhz frequency.
It says better antenna reception, using other than straight, Dowsing rods.
I've been using my triangle rods for a few yrs now, I quit using straight rods when the signal strength got too weak for them..
