Why is it so great?
Looking for a solution giving gain similar to 2 bay vertical dipoles with perfect omni-directional coverage and have some space available at the top of a roof or a tower? Than this is the antenna for you. 2-dipoles mounted at the side of the tower will not give perfect omni-directional coverage; this antenna at the top of a tower will. Produced to exacting standards using state of the art electrical and mechanical designs resulting in superior performance and long service life. When measured against a standard 1/2 wave dipole the ExterminatorII® delivers close to a massive 5.15 dBi (3dBd) gain across the entire FM Band. All RF connectors are PTFE components with specifications that exceed required ratings. Antenna arrives fully tuned and assembled the ExterminatorII can be installed on your tower or mast in a matter of minutes.

Remember to write your desired frequency during check-out under comments, we will pre-tune your antenna for you. You can always tune your antenna alone with SWR meter and instructions. Note that although antenna is tuned at the factory it is sometimes necessary to make a small adjustment depending on for example nearby objects etc. Some parts may also move slightly during shipping so remember to re-tighten all screws. Antenna ships in fully assembled form, but the two sections are collapsed for easy transport. You will only have to release two screws and extend the two telescopic sections all the way to the two black marker circles, than fix the screws again.

Advantages:
– Stronger and resistant to sea-salt corrosion
– Perfectly circular coverage when mounted on top of a tower/pole.
– Matches or outperforms 2 dipoles
– Easier to mount than 2 dipoles

Disadvantages:
– Not wideband, requires tuning (we do this for you)
– NOT SUITABLE for people who don’t know how to operate SWR meter or perform simple antenna tuning (take wideband dipoles or multi-bay systems instead please)
