I have seen that unfortunately DJI does not sell antennas for the spark remote separately, however I was wondering if I could get them via customer support request. Is this an option dji would allow?

HI, thanks for the inquiry. Unfortunately, DJI doesn't sell antenna for a remote controller of the DJI Spark since we're not recommending our customers to fix the unit by their self as this process would void the warranty of your DJI Product. However, if there will be a problem with your remote controller physically, we would recommend sending the unit to our repair facility and we're the one who will rectify the problem with your unit. Thank you for continued support.

Thanks for the reply and excuse my late reply. There is no particular issue with my remote. This was to get some more information on a cosmetic option or in utalizing and amplifier connected to antennas while keeping the originals unaugmented. None the less thanks for getting back with me
