Any successful antenna upgrade stories ?. Which model, why, how much improvement did you see ?. AIOv1 or v2 ?
Is there a great all round SDR antenna or is there no choice but to have a set to suit the band you’re scanning at the time ?.
AIOv2 experience on various bands ?, any that are simply unusable ?
Supplied with my AIOv2…
If that was mine, I’d move the gps antenna to the spot on the far right. It has the most distance to the next connector.
I placed it there to give easier power switch and SD card access. The SDR aerial was going on the side but I didnt get the socket in my kit (ordered from Hackergadgets and out of stock parts from Aliexpress). Socket that arrived today from Amazon has a too big back nut 
…
That brass is super soft. File down 2 opposing sides and run it….
Still getting full speed yet noticed today, back corner of the house wi-fi -70dbm. Removed the Hackergadget wifi aerial, -70dbm. Surely something is amiss here !
SDR antennas are going to depend on what you are trying to do. The one that came with the kit seems great for fm so far.
I upgraded the lora antenna to a 900mhz whip antenna that I use for most of my meshtastic gear.
I am upgrading the Wi-Fi and Bluetooth antenna but that’s just for visuals honestly.
If you want to get fancy you can buy a nano vna and test antennas at the frequency you care about.
Dumb question, is your antenna rp sma? I connected an rp sma wifi antenna to mine without noticing and it mostly worked for wifi but Bluetooth choked. A real sma antenna fixed it right away.
If you remove the original wifi antenna while stood in a weak spot do you see a difference in the dbm value ?
The cm5 wifi or th aiov2 wifi?
Classic. For some reason the boot config.txt had reverted to ant1, now ant2 again.
Ant1 = -86dbm
Ant2 = -68dbm
A slight improvement as expected, will try a larger wifi5 antenna asap.
How are you checking dbi? I’ll check in a bit. Wifi is bad at the end of my house so it could be a good test
first one is my antenna attached, second is no antenna
