Thanks for the replies everyone, yeah it seems like i need that adapter, i'll pick one up.
Regarding the Yagi being designed more to transmit than receive, i'll have to lookup some threads on what people actually use the Yagi for and how they use it
I just thought it was strange that the bundle came with an adapter that seems basically useless for anything that's actually in the bundle, i thought maybe they sent the wrong one, or there was supposed to be a 2nd adapter which was the opposite of the one in my photos, also on the shop page for the bundle, it lists "SMA to RP-SMA adapters", adapters being plural, which also made me wonder if i was in fact missing a 2nd adapter...
I'd be interested to hear from anyone who actually bought that bundle, as to whether or not they only got the same single adapter that i did
