How to choose a 1:1  balun? There are loads for sale on ebay so how do you choose?
Well you can buy one for as little as £16 then you might as well just not fit one... why? Here is why! What do you want from a 1:1 balun... ummmm first you need to form 50 ohm coax (unbalanced ) to a balanced antenna (dipole ect), right ok thats what most baluns on ebay will do (well maybe not the cheapest).
But you need a 2nd function on the1:1 balun which is FAR more important and I guarantee that nearly all so called baluns DO NOT meet the minimum standard of 20 db common mode attenuation (rf on the outside of the coax).
Some offer 0dB... yes none, nothing!... You need at lest 20dB or higher this is so very important when choosing a 1:1 balun if the seller does not state their data then there is not worth considering please watch this youtube video on baluns its in your interested in learning more https://www.youtube.com/watch?v=kMlKfHHR8FY
