Yes a clover leaf antenna set will be used, I have a few dozen of them from my other birds......I like the combo of value priced items, Very good choices.
I might add a pair of something like this Clover Antenna set. but not critical
And I'd be curious as to how much latency(Delay) you might get from the Mobius Live out to the googles, but you're not racing this thing, its for practice. You could use a TVL600/700/800 instead, for the FPV, But I think the Mobius should work too, with possibly better quality.
Can't wait to hear your first impressions
