content: Got tinySA/LiteVNA for fun but I connect and disconnect them more times than I expected.I checked the usual places from where I get stuff (Mouser/Eleshop/Reichelt/even Amazon) but either I am too dumb or they are not there.So, where do you find this SMA port savers ?(with bonus thanks for places that might have other GHz RF'ies like mixers and filters)

content: Haven't tried them, but I could only find 90 degree Angle on Amazon for Chinesium parts :https://www.amazon.de/-/en/Female-Adapter-Right-Degree-Connector/dp/B08B1PGPDYFor straight through Chinesium, would need to use Aliexpress or similar I think.https://aliexpress.com/item/32946122594.html?gatewayAdapt=glo2nldBit of a crapshoot how it will perform though in the couple GHz range.

content: Quote from: rteodor on August 12, 2022, 08:51:02 pmI bought mine off eBay. I have tried several different types and they all work well (only tested to 900 MHz.) You can get them from Digi-Key but way more expensive.https://www.ebay.ca/itm/181091044796?hash=item2a29de0dbc:g:LtoAAMXQlgtRv~SF&amdata=enc%3AAQAHAAABEMzfNfS3tO1KovfUuUR9jNDhUAqCS4NH3ostM4x8q9L2T%2BMrM4R7zF5nHYEvPP7a%2F6kQ1MCqQSHssmhD4190FyOftc2qfzpbAsxEQzJuRRQSjo7Kk4y5oGJbPrRJGHy6YhVlik%2FZGV52IeqIYkGX07Kq1UF6NJO8RV4MPCpnfbtugkqxr82XdxRUxNlWZjfjLnRMmGMffp%2FCiYWOhQeeSjH5%2Bse2Wwjk0le%2F%2FfXyqgOeRuKNR5yMwgZZw9ZVBbJCv0bgxRej6gWwVX0b0ITBythbw5hXMqUtGA0uaXJOEXQUvGbTaPWx3MUi6vtlEf058BQGb69Nd58N%2BpxyJ%2Fd%2FgX9Q%2BfuN3YdBjAqBlmj5VGVL%7Ctkp%3ABk9SR7K48ZHVYA

content: Quote from: MarcoJust the domestic RF FM up to 2.4GHz. I'll save fine radar applications for another life.Quote from: TheUnnamedNewbieGood point. I also got some not so cheap atenuators that in total were more expensive (~100EUR) than the tinySA (~50EUR).So to protect the atenuators now I need the expensive port saver ? Wouldn't be better to just get some quality cables instead and leave them connected ?
