Description

The listing, What are they??? has ended.

I don't know what these are. They are from when I used to have cable TV.
The skinny ones are 2-1/8" long, approx 3/8" diameter. One is marked "10", the other "9" (or maybe it's a 6).
The fat one is 2-1/2" long, about 3/4" diameter. It is marked "Eagle Comtronics Patented" and "EXD -H"
Each has a male and female RF connection.
If you know what they are, please let me know.
If you can use them, place a bid.
Winner gets choice of both of the skinny ones or the one fat one. Whatever they are.

Questions & Comments

I believe these are bandpass filters to reduce noise in the video.

As I stated, I really don't know what they are for.

A friend says the bottom fat one is a muffler for a model aircraft / boat glow engine
it has the pressure nipple on the back. Dunno what the two other ones are. They might be filters to eliminate cable connection.

Absolutely not. As stated, "Each has a male and female RF connection." When the fat one was connected to the cable TV wire I could receive premium channels like HBO. But that may be specific to the cable service provider. But thanks for trying.

They are filters to cut out electronic noise on a cable line. Especially if you had a phone system working on the cable line also.

These are filter that let a person get or not get certain channels on cable some let hbo cinemax or other pay channels but they have since changed to digital boxes so they are only used in rural areas now i used to work for a cable company
