My antenna desig is based on this and i wil post here my findings, My calcuations were calculated by the Antenna XLS doc, and i did some quite specific calculation of coil length and coil turns so if theis XLS doc is correct my coild should be correct…
I also considered a adjustable mast and after the light of this info i seriously think i will need to make my mast adjustable but that is very simple, i just need to unscrew it, cut neer the 3/4 of the way up and get a few feeet of 3/4″ copper pipe to incert into it and its adjustable..
SO i promis when my transmitter is modified and i hook it up i will give a fair judgement of this design, and then make my antenna adjustable and see if that helps and report those findings.. if that doesnt get me good range i will redoe the entire thing as reccommended and see if that helps… the plus is my grounding and dirt work are doen so i dont have to redo everything if it doesnt work out..
If my coil is way out of wack, i can still tap it with a dremmel and a soldering iron.. so it may not be a total loss 🙂
I do however think that making the antenna the way i did, by using the PVC as the mount for the radiator mast, coil and the post to secure in the ground, made it much simpler and cost effective to build..
We all making this up as we go.. so I’m calling this a learning experiance if it works or deosn’t.. I mean if i dodnt want to mess withbuilding my antenna and or other parts of my station.. i would have either purchaced a antenna or bought a rangemaster.. For many the hobby id the art of broadcasting and for others its the art of building and tinkering.
