[TowerTalk] Legal Limit Antenna traps

[Gene Bigham]

Can anyone suggest some bullet proof antenna traps for a trapped inverted V 
for 40/80 and 160 I need a pair for 40 and a pair for 80 and will use 
stinger on end of antenna to resonate to 160.  The unadillas I just 
installed melted after being meticulously tuned to low swr 1.2:1 when only 
500 watts applied.
Did I just get bad traps or is there something heavier out there?
