Oops... Antenna doesn't disassemble that way. Help?

I have a cheap 220mhz magnet mount I was going to use on the metal roof for a temporary setup. I grabbed the antenna and tried to unscrew what looked like the coil from the base, and felt the coax pop inside. Oops. I cut the felt open and yep, twisted it right off the solder lugs. No big deal... but wait, there's a stray little ceramic capacitor in there. Huh? I'm far from an expert on antenna theory, buy I don't recall ever seeing a cap in an antenna base before. Problem is, I cannot tell if it was soldered between the center conductor of the coax and the antenna element or if it was soldered between the coax shield/ground and the center conductor/antenna. It's still attached to the center solder lug of the brass antenna base. Any insight? Is it advisable to remove entirely, or should I solder it back to where it came off of?

Lots of antenna types need capacitors or inductors or both. What brand and model antenna is it? Without knowing that nobody can help you.

It's just a cheap magnet mount 220mhz whip antenna, I'm guessing 5/8 wave, advertised as having 2.6dBi gain and handling 300 watts. RG58/U coax. It's nothing special.

How long is the whip? If it's a 5/8 wave for 220 MHz it should be around 32" including any spring and the metal piece the whip is attached to. Usually those type antennas have a series coil and no capacitor. Advertized gain (which is probably a lie anyway) and power handling capacity are meaningless at this point.

This seems to meet all the described requirements (especially cheap)

Pretty much it... though marketed as a "Harvest" brand product. No doubt they're the same.
