The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

14221 900MHz 3dBd Omni Antenna w/Type N Female & Mounting Hardware
 
The radio requires the purchase of an antenna. A choice of six antennas is offered. The 14221 has the highest gain (3 dBd) of our omnidirectional antennas. It is suitable for base station use where you need to communicate with multiple stations located in different directions. It's rugged FM2 antenna mounts will accommodate a vertical pipe of up to 2.5" (6.5 cm) outside diameter. The antenna has a TYPE N female connector and requires an antenna cable to connect it to the radio.
14204
14204 900MHz 0dBd Omni 1/2 Wave Whip Antenna w/Right Angle & RPSMA Male
 
The radio requires the purchase of an antenna. A choice of six antennas is offered. The 14204 is a unity gain (0 dBd) omnidirectional antenna. This antenna must reside inside a building or enclosure. It's right angle knuckle joint can be oriented vertically or at right angles. The 14204 attaches directly to the radio (antenna cable not required).
