That part number is a Maxrad 34-40Mhz mobile antenna. A good choice for what you are doing. 27-31 might be the coil model, maybe.After looking at the antenna i'm not sure if it's a maxrad I don't see any markings on that say maxrad on the crome part or less it came off after years of use. In the inside and it has 27-31 not sure if it's tune for that or it's the model number.
Not surprised it won't work well elsewhere. An antenna specifically designed for low band wouldn't necessarily work well elsewhere. There is a lot to be said for having the right antenna for the application. Trying to find a high gain antenna that covers everything is difficult. Sometimes specific antennas tuned for what you are trying to hear work best. An antenna switch can be your friend here.
