We still supply the Velcro with each unit to support older radios. With modern radios which are very small we recommend putting the rattail under the belt clip when needed. The original design used Velcro to attach to the back of the radio. This is why we get such positive reviews for our design.

The Rattail dangles free of the radio body and becomes an ideal second antenna element creating a true half wave dipole. The wireless Rattail mounting method does not suffer from this problem. This results in a several hundred percent loss in transmitted energy from the dangling element. The radio energy in the dangling wire gets absorbed largely by the base of the radio it almost touches. There is a great advantage the Rattail design has over adding a dangling length of wire to the antenna mount. Received sensitivity is also increased by the same amount. A 5 watt handheld radio becomes effectively like a 20 or 40 watt radio, thus increasing its ability to get a signal through. This device only works on handheld radios. Boaters will double their range from a small craft to land.

This makes it very useful for emergency rescue operations where rescue workers are having difficulty getting their message through to a base station. Thus more energy is delivered to the horizon. This increase results from a transformation of your radio’s 1/4 wave vertical antenna to a 1/2 wave dipole antenna. It makes a great improvement to Marine and Aircraft handhelds where the rubber antenna is very inefficient.Īn increase in transmitted energy of 9 to 12db (800% – 1600%) is seen when measured at a distance of 2 kilometers or more.

Custom versions are available for 6 Meter Band, Marine, Aircraft or up to frequencies as high as 250 mhz. This passive device attaches to a handheld radio operating in the VHF Bands. The RatTail Antenna Booster is a patented technology.
