I received my DIY receiver kit a couple of weeks ago, but have not been successful receiving more than a handful of packets from I4F1-APAC here in Tokyo. I don’t know what the typical beamwidth is for this patch antenna, but outdoors on the balcony slowly tweaking around where my satfinder app suggests I should be pointing the best I’ve been able to achieve is an SNR of just over 2 dB. I’ve tried crudely shielding the LNA with aluminum foil and separating the LNA from the Elonics receiver by a meter without noticeable improvement. I tried out in a neighboring park in an attempt to avoid any local noise sources without appreciably better luck.
Just how critical is antenna position to getting a usable signal?
