as for the traps they should be ok i used one for 20 yrs. i did have to add
insulation to the outside about every 4 or 5 yrs. i used red insulation
dope or you can use black liquid tape to seal the cracks. as for the coax
if it is the non foam type and not been outside it should be ok you can
short the ends and use a noise bridge to check for loss . old arrl
handbooks tell how,
if it is rated at a KW AM then you have a very good trap new ones are not
rated for AM or RTTY. only problem i see is the rg58 taking a KW AM.. SSB
maybe 800 watts .
