In order to produce the best gains an antenna needs to be unidirectional, meaning it must be aimed directly at the transmission source. With this antenna it is held straight out and moved in 10 degree increments until a signal peak is detected. This peak represents the direction of a cellular transmitter. For best results a complete 360 degree circle should be made as there could be multiple towers to receive from and there could also a peak when the antenna is facing exactly away from the antenna as it is perfectly lined up but facing away. This "back course" peak would obviously be much weaker as the antenna is designed to be point at the tower not away from it. Similar to the magnetic antenna, the directional antenna is a remote mounted design. This time the antenna comes with 15 feet of RG58 cable. RG58 cable is visibly larger and is superior to the RG174 cable used on the magnetic mount, in every way. This is necessary when using longer lengths as RG58 looses only .18 dBm per foot. Using 15 ft of included cable gives us around 2.7 dBm of signal loss. However the directional antenna produces a whopping 11 dBm of signal improvement. This provides a net gain of 8.3 dBm. Make no mistake, this is a lot of signal improvement. This means that if any signal is present in the area of deployment, this antenna can be used to make the camera transmit successfully.Finally there is an intangible factor to be considered with any remote mounted antenna, altitude. Altitude does wonderful things for cellular reception. Since cellular transmissions are a high frequency, short wave length type of signal, the do not adhere to the curvature of the earth. That means, that for all practical purposes, cellular transmissions are line-of-sight signals. Having the ability to mount the antenna almost 15 ft higher than the camera can provide a huge boost to usable signal, simply because it has a better "view" of the cellular tower that it is pointed at. This altitude gain can also compensate some amount of terrain blocking due to hills or valleys. Having said that, it won’t compensate for placing the camera in a deep ravine, remember there has to be some signal present for any antenna to work as they don't invent signal, they just receive the ambient signal with more efficiency.The directional antenna comes standard it what is affectionately referred to as "snow camo". However it readily accepts a customized finish from a can of spray paint or any other type of crafty finish that can be thought up. Keep in mind that it is an antenna, so things like metallic paint (seriously metallic paint for camo?) or large amounts of items adhered to the antenna for camo should be avoided. The best results seem to come from the obvious color choices such as OD green, tan and brown. A single color or combination of these colors based upon the area of deployment, go surprisingly far in making this antenna blend in.
