I recently ordered replacement 900MHz 1/2 wave antennas for my fleet of DTR650 radios and found not all 8505241U04 900MHz 1/2 wave antennas are created equal. My original set of antennas was getting beat up and I ordered a bunch of new ones from a different seller on Amazon this time around. The antennas were advertised as OEM Motorola 8505241U04 antennas and that's exactly what I got. They are the real deal from Motorola. What I noticed is they are slightly different from my original set of 8505241U04 antennas.
Check out the pics below. (DTR650 box used for the background in the pics.)
The OEM Motorola 8505241U04 antenna is slightly shorter than the other antenna and the dielectric in the connector is blue instead of red. The OEM Motorola 8505241U04 antenna also has /\/\ Motorola 900 molded on it. Both antennas were ordered under part number 8505241U04.
Could the longer red colored antenna actually be tuned for 800MHz instead of 900MHz? The OEM Motorola 8505241U04 antenna specifically lists 896-941MHz coverage on the packaging and is exactly what I want for my DTR radios. I recall a discussion in a thread a while back about Motorola's color coding on these antennas where red was for 800MHz and blue was for 900MHz. Anyhow, my new set of antennas for my fleet of DTR650 radios are the real OEM Motorola 8505241U04 900MHz antennas. I wanted to give a heads up that not all antennas ordered under the 8505241U04 part number are the same. Be careful with who you order them from.
