Re: What accessories do I need for a TinySA Ultra?

Also some higher-power attenuators. I have some 5W, 10W and one 50 watt attenuator (that one is 30 dB). If you're concerned about wearing out the connectors on the TinySA, just get a few straight-through or right-angle SMA male to female adaptors. Put one on the TinySA and leave it there. Then it will wear out, not the one on the TinySA.
I don't know if you'd need a DC blocker or not. I do not have one and never needed one. All of the RF equipment I have used already had DC blocked and only had RF on the output. Note, if you are going to connect something with higher power and suspect DC is on the output, you'll need something a lot bigger than the one you referenced.
I have various telescoping antennas that came with various SDR modules I've purchased over the years. Just about anything will work. One of mine has an MCX connector on it and I had to come up with an adaptor for MCX to SMA.
Also, as an addition to my last post, you can stack the SMA adaptors. I have two 20 dB and one 10 dB attenuator stacked to use with my HP 435B power meter. The maximum power to the 8484A power head I have is 10 microwatts.

I have 2 watt SMA attenuators (male on one end, female on the other ehd) covering 1 to 10 dB in 1 dB increments, and then more attenuators up to 30 dB. I have attenuators rated to 18 GHz because I do a lot of microwave stuff, not just with the TnySA. If you don't plan on going that high in frequency, the ones rated to lower frequencies are fine. I have a bunch of SMA to BNC, N, UHF and TNC adaptors of various types (male to male, male to female, etc.) Also some cables longer than the ones that come with the TinySA with male SMA's on each end.

I'm new here and new to my TinySA Ultra and NanoVNA. Trying to keep it affordable, I'm just trying to figure out what accessories I should buy first and which ones I should still buy but can wait until later. What attenuators should I get first? I have an assortment of connectors/adapters and I have these two attenuators, . And a 15w 0-500Mhz Dummy Load
Is there anything I should buy to protect the SMA connectors with adapters on the TInySA like some people have mentioned? And do I need anything for the antenna? Someone mentioned a DC blocker like this, Is there an upgraded antenna worth buying? I'd like to have a second one on hand as backup anyway.
I'm wanting to test out some Ham radio handhelds and my mobile Anytone AT-778UV Ham Radio. They are UHF/VHF. And then I'd also like to test out some CB radios.
I've been reading mixed reviews on everything so I figured I'd ask here before I started ordering things I don't need or end up ordering the wrong things.
Thanks for the help.
