Hi, you're a lucky person having your own olive grove! Kalamata are very nice, haven't had any for years, but remember fame is deserved.
Only read a little about RF signals, so I wouldn't put my hand in the fire to guarantee it won't have some effect, but nor do I see why it should, only thing I can think of is radiating outwards at the bend in unwanted direction perhaps - but from a ground pin? Done with care not to damage connector, which obviously you will, guess okay solution, otherwise they wouldn't manufacture right angle version as well as straight.
Maybe member more versed in RF will have a definitive answer, as wouldn't want to mislead with incorrect info.
