Do you still use the GulfAlpha 'Easy Sat' antenna?
I'm looking for any advice on improving performance.
I have already installed the diplexer as shown in the article below but it
seems I'm getting no good signal on the 70cm uplink.

Buy a diplexer, and connect it as shown in the linked article:
I also tilt both of my Yagis so they're 45* to the boom, which makes
them 90* to each other.
Yes, I lose some signal on terrestrial use, but ti helped cut the
coupling, and desense, down quite a bit.
