Two questions about my current home brew yagis in progress.... one VHF, one UHF. Both are 50 ohm, isolated element, dipole-fed. 1. What do I do with the aluminum boom? Float it, tie it to the coax shield, earth ground? Also, I have a good handle on the choke design for both using the appropriate ferrite toroids and beads. However given they will be mounted next to each other (ie satellite work) 2. Do I need to worry about affects on each other or just filter on each yagi for it's resonant frequency range?
