that I have found the printed instructions hard to follow as it relates to tuning this antenna is a real understatement -- I could really use some assistance from the group. Here is the situation: The owner wants to operate from 7050 to approximately 7250 -- so the mid point would be 7150. With that in mind, I have the following questions: 1) What are the tip lengths for the Reflector & Director, when a center operating frequency of 7150 is required? 2) Are the two (2) individual element final resonant adjustments with a meter done with individual elements or with the assembled antenna raised above ground? 3) Tuning of the Reflector is done with the balun and feed line attached to it and the Director "open", according to the manual. Is the Reflector also "open" when adjusting the coil on the Director for lowest SWR? Asking this question suggests that the answer to 2) (above) is that the entire antenna is assembled above ground for checking rather than the individual elements. I would appreciate hearing from anyone who has this exact antenna -- maybe you've been through this same series of questions and hopefully found the answers. The final resting place for this new antenna will be atop a brand new US Towers 88' crank-up. 73 de Paul, VE7AVV StoneyGround Station -|<*><*>||<*><*>||<*><*>||<*><*>||<*><*>||<*><*>||<*><*>||<*><*>|- "All email from this address is checked by Norton AntiVirus 2003" -------------------------------------------- Force12Talk mailing list provided as a service by Force 12 Antennas, Inc.
