APX APX Replacement Whips (E/M Wave)

[devicelab]

I purchased both 1/2 and 1/4 wave whips for the APX from E/M Wave. Performance is quite good on both but the stubby really impressed with a 1.1 SWR @ 799 Mhz. The 1/2 wave was roughly 2.0 @ 799 Mhz.

For the price, this is a great value. Note, the antennas are not designed for GPS. They also make a multiband model that is roughly half the cost of the factory Motorola -- one for GPS and one w/o GPS support.

1/4 wave --> EM Wave EM-P90111-SF - Motorola 800 MHz Antennas

1/2 wave --> EM Wave EM-P90110-SF - Motorola 800 MHz Antennas

I'll post a couple of VNA screenshots when I get a chance.

I admit I'm a little partial to the Motorola stubby but the E/M Wave performance is impressive.

Does the bottom "skirt" completely seal with the antenna connector? A lot of aftermarket APX antennas don't, and this allows moisture and dirt to get into the threads and leads to corrosion.

Yes these are designed specifically for the APX. If you look at the site they have antennas for Harris and Kenwood radios.

Well, not quite. They were designed specifically for the XTS series long ago, they just happen to also be compatible with the APX series.

Partially true. The Multiband antenna was designed for the APX.

I have 2 OEM antennas (from big M themselves) for the APX and neither skirt fully seats around the base....
