Tony, a corporate-fed antenna like the 408 will not exhibit downtilt or uptilt when operated out of it's design range, however, it will exhibit slightly less gain. Chuck WB2EDV - Original Message - From: Tony Alviar (Home) To: Repeater-Builder@yahoogroups.com Sent:

Optimum vertical spacing is between 0.85 and 0.95 wavelength as measured between element centers. This may or may not be possible due to constraints of the phasing harness, so you may have to settle for something else. Chuck WB2EDV - Original Message - From: motarolla_doctor
