Antenna Gain

[species8350]

I have Yagi type tv antenna that has excellent forward gain.

I would like to sacrifice some of the forward gain to increase the gan at the rear.

Can anyone suggest a simple way of blocking some the directors (without removing them) in the hope of increasing the gain at the rear?

Thanks

What is the make and model number of the antenna??

Are you attempting to receive signals that arrive from opposite points of the compass? Or as in your previous thread, are the signals of interest aprox. 90° apart?
