/diy/ - Do It Yourself

I'm preparing for a mid range (4-5km), line of sight, fixed wing flight. I have historically used a 1.2ghz vtx, but will be flying with someone with a better 2.4ghz setup on the same polarization (he gets ibcrazy stuff where I get chink shit). So instead of buying other 1.2ghz stuff, I want to get some 5.8 gear. Most of my flying is fixed wing and high 200+ meters and in front of me. I'm looking for the best chink setup i can get for this. I think the realacc stuff has potential. Any experience here or opinion? My principal concern is that if the pagoda antenna is vertical, it will be broadcasting signal at 200+ meters high instead of to the ground. If I angle the antenna diagonally, that may help for a range of distance, but may struggle elsewhere.
