QUESTION Antenna

Hi, i have a RTL SDR (soon maybe I’ll upgrade to a SDRplay RSPdx) and i want a antenna for Ghz, i already have a Diamond X300 for listening to 2m/70cm and a dipol antenna for 40m SWL, so whats the best antenna for listening to Ghz (1.100Ghz - 2Ghz)? Nagoya, Diamond or Comet?

(Sorry if thats the wrong subreddit)

For SDR, it's hard to beat a discone type antenna - VERY broadband receive.

I have a set of conical-spiral antennas for EMC testing in the microwave bands.

They are insanely-expensive brand new. Spend time on eBay and you can find them.

Here is an example;

I have spirals and also conical spiral antennas they are fairly small.

Buying new it would be thousands of dollars. eBay and you can do it for $50-100 each.
