RAIGEN Magnetic Antenna Base for Helium Mining Antennas N-Type Female, 6.5ft Raigen-200 RP-SMA Male Cable, for MNTD, RAK, Bobcat, Syncrobit, Sensecap Helium Miner, Indoor use only

I’m using this mag mount antenna for a 900 MHz antenna. It holds up the antenna well and it’s a good size. I appreciate the cable length and quality. With UHF frequencies, the loss in the cable can be an issue, so keeping it short is a big win. Loss was around 0.5 dB when measured on my VNA. Naturally it is more efficient when placed on metal, but no SWR issues with my antenna. Overall happy with it, my only issue is why is it called indoor? I feel like a mag mount goes on a car or other exterior metal object. I have mine inside right now, but it has spent a few days outside and no observed issue. Antennas are best outside so I would think this product would want to support that.

This base allows a clean solution for setting up an antenna in your window. It doesn't require you to stick anything to the window itself, as the base is heavy enough to keep the antenna upright. The 6.5ft cable could be a bit longer, but given its rating, you'd start to lose more signal at longer lengths.
