I go with Option #3 Put the vertical on the roof of the house with as many possible radials as you can. Don N8DE _______________________________________________ ______________________________________
Rag, The spacing between adjacent elements in a LPDA is NOT a function of highest/lowest frequency. Do some research on LPDA design and you will discover that the 'graduation' of spacing and element
A round balloon can be made to 'function' in a similar manner by placing a [cardboard or plastic] disk of sufficient size beneath the balloon. This will act to give lift to the balloon, maintaining i

Remove the balun from the feedline and connect the coax directly to the feedpoint. I KNOW the balun is 4:1 ... that's not the point here. If the balun is the problem, you should see a difference in '
