Jack rv antenna

[PT RV`er]

I have replaced my factory antenna with the Jack rv antenna several months ago. I bought 2 antennas, one for the rig and another for a stand alone install where I store my rig. The one in the rig is working fine. My problem is trying to locate where I left the power amplifier that came with both the antennas. I can`t believe I`ve misplaced 2 amplifiers. I need this part for the stand alone antenna to hook up to my external tv coax connection. I have a cover over my rig so I can not raise the roof mount antenna. Hence the stand alone unit.
So I`ve been all over the internet trying to find another power amplifier for the antenna with no luck. The one that came with the antenna is a 120v to 12v converter with power booster.
So my question is, will any amplifier work for this , or do I need to stick with the original amplifier if I can find one?

If you come across your manual you will see : Power Injector (included)
• KING #PB1000 - power supply, white. .... Google that and you will find many rv stores that carry them for about $20. The booster in your rv from the Wineguard will power the one on the trailer just fine. JM2¢, Hank

These are 12v dc but you can always power them fro the trailer.
