Is there a way to test the antennas?

[LeKeiser]

Hello all,

Might be a stupid question, but is there a way to make sure that the antennas of any router are working?
I've got a R7800, and before I had and sent back an Asus RT-AC87u, a RT-AC88u, and a R8500. I've sent them back for different reasons but that's not the question (the 88u gigabit ethernet ports went down once, had to turn off and on the router to get them back...)
I'm just wondering if there is a way to make sure that all the antennas are working, emitting or receiving, or if something is wrong, if one is down, or...

Thanx for your thoughts

If the product has removable antennas, remove all but one antenna and CAP the others with SMA caps.

Then move a room or two away from the router so that leaked RF from the capped connectors doesn't affect results. Try to connect a device. If it connects, antenna is working. If not, it isn't.
