I'm gonna say no way are those two antennas you listed are better than the 15-1890. First, the 15-1838 is $29.99 and and doesn't use double helical elements like the 15-1890, but instead uses a standard loop encased in plastic. The 150-1862 is no longer manufactured and is a phased out product. I tested the 15-1890 and it's performance for regular analog VHF and UHF is pretty good and for the price of $24.99, it's a better deal than the two you mentioned.
