I don't know what clock you have or what's it's clocking but in my experience clocks have hugely inflated prices. My clock is made from a Russian missile. Pre Ukraine war.
Most commercially available clocks have a Rubidium clock the size of a grain of rice. Which is not good.
Cybershaft clocks are good but their cables aren't.
Anyway you should buy a real clock cable which will cost $1000 or more.
The clock cable I use is from Viard Audio, a French company.
Good Luck
