Without a doubt, there are no other 8 way stacked dipoles on the market priced like this. Don't look any further, this is high quality, high gain, high bandwidth and the only low, is the price.
This antenna has super gain at 10.8dBi, this is more than 10 times power increase, basically huge!! But if that is not enough, this antenna will operate over 87.5 to 108 MHz with an SWR of less than 1.5 with no retuning. We use this antenna with our 1400W ERP system
The radiation pattern of this antenna is super narrow which makes it super efficient. Virtually nothing below this antenna and virtually nothing above this antenna. All the energy injected into this antenna is focused and concentrated in a narrow beam to the horizon. This means you only put the power where it is required, there's no power wasted up into space or down into the ground. We've made a Youtube video here showing this during one of our tests on the antenna when it was on the ground https://www.youtube.com/watch?v=-SnBnkvSTSU
We've been making this antenna for about 5 years, however it is made up using our standard dipoles that we have manufactured for 20 years which the hardware is tried and tested in virtually every area of the world with high reliability. It is suitable for any location without suffering wind, corrosion or other weather problems.
All the dipoles that make up this antenna contain a matching coil to reduce the antennas natural impedance of 72 ohms to 50 ohms. To protect this and the LMR400 coaxial feed from water and other weather related elements, all the feed points are filled with resin.
Normally the dipole system clamps as high off the ground as possible to a mounting pole of at least 4 meters in length and between 25 and 38mm in diameter which you need to provide and engineer yourself.
