Is it possible that using a SMA cable degrades the signal? #6
Description
In the OpenMetBuoy project, to get space for the antenna, we use an SMA cable extension.

I thought that would be fine, however, a colleague (@tn77) found that using a 90 degrees SMA adapter (looks similar to https://www.digikey.no/no/products/detail/rf-solutions/ADP-SMAM-SMAF90/5845786?utm_adgroup=Coaxial%20Connectors%20%28RF%29%20-%20Adapters&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Product_Connectors%2C%20Interconnects&utm_term=&productid=5845786&gclid=Cj0KCQjwjbyYBhCdARIsAArC6LKO7ka-i0bTQBgPm2VJWQSeuV8KflvsWT5X2A7p_a7kdOWd6NJU5nQaAl2DEALw_wcB but @tnn77 can put the link to the one used maybe?), the signal reception for iridium seems quite a bit better.
Any thoughts about this? Can it be bad ampedance matching or something like this that is problematic with the SMA cable extension?
