I'm looking for the small screw on tip of the KX-T7885 cordless antenna. I have a customer that lost his. If possible please include the part number...tks...

All I can come up with is the complete antenna.
I"m looking right at one and it's all one piece.
Are you referring to the antenna on the base unit.
The rubber coated ferrite antenna on the handset
is: PSSA1019Y for $10.62 from Panasonic parts.

The telescopic antenna on the base unit is:
PSSA1005Y and lists at $11.19
That's all I can do for ya.

I thank you for the info. It was allot of help. It's the antenna of the actual cordless handsets not the base. tks.... for your time.
