Introducing the EXTERMINATORII
®
87-108 MHz High Power VHF Broadcast Antenna
The ExterminatorII is a powerful omni-directional FM Broadcast Antenna based on the successful Sirio shortwave
antenna with several important modifications and improvements. ExterminatorII® gives the same range as 2
vertical dipoles and when mounted on the top of a tower it gives close to perfect omni-directional pattern. Produced
to exacting standards using state of the art electrical and mechanical designs resulting in superior performance and
long service life.
The high build quality and DC short protection will provide peace of mind to stations who want to stay on air. ExterminatorII®
withstands the toughest environments. ExterminatorII® ships fully tuned and assembled and can be installed on your tower or mast
in a matter of minutes.
ExterminatorII® delivers a massive 5.15 dBi gain across the entire FM II Band. All RF hotspots are teflon/PTFE components with
specifications that exceed required ratings. Once tuned to your frequency the ExterminatorII® will never go "out of tune" and will
not be affected by rain unlike some other versions.
Remember to write your desired frequency during checkout at the time of ordering (under comments); we will tune your antenna for
you. You can always re-tune your antenna alone with antenna analyzer or SWR meter. Note that although antenna is tuned at the
factory it is often necessary to make a small adjustment depending on how installation is performed. Some parts may also move
slightly during shipping. Antenna ships in fully assembled form but the two telescopic 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.
What’s new in version II
- Significantly improved connector assembly, better than any other design out there at time of release.
- Improved gamma match, better than any other design out there at time of release.
Advantages
- Near perfect circular coverage when mounted on top of a tower/pole
- Matches or outperforms 2 dipoles
- Usually easier and also cheaper to mount than 2 dipoles
