[TowerTalk] coaxial gas arrestor selection

[Jorge Diez - CX6VM]

Hello,
 
I need to buy coaxial gas arrestors, to use in HF antennas, with 1.5 KW
 
I found in the internet the AlphaDelta TT3G50 and the ICE 303/U
 
What do you recomend?
 
Maybe another one instead of this two I found?
 
Thanks,
Jorge
