Just chopped the fibreglass webs out and now no change, I would not have
thought it would affect this coil, so something else must have altered since
two days ago (Had to work) affecting the way the SWR is reacting.Pity, I was
pleased with the result, now to try to increase the Q of the coil without
altering the resonance, I cannot go longer on the top wire as it would
extend over my property boundary, hence the loading coil.73 Max M0GHQ
