[Antennas] Ham stick dipole

[Frederick]

Hi
     Wanting to build a vertical dipole the quick and easy way, I bought a 
pair of 75 meter hamsticks and the matching dipole bracket. I used a noise 
bridge and SWR meter and tuned each hamstick to be resonate just above 3.9 
MHz. When I then mounted both antennas on the bracket the resonate frequency 
dropped to 3.4 MHz. Any ideas on what happened? Do I really need to go 
through the entire tuning process again?
     Thank you.

God bless,
Mark

God loves you!
