Mounts Low Angle Radiation

Be sure to pick the mount style that will best support the antenna ona particular boat. When using a two-piece antenna system greater than 10' in length, an upper support clamp is necessary. For antennas of 14' to 18', the upper clamp should be 3' to 5' fromthe bottom. For antennas of 18' to 23', the upper clamp should be 4' to 8' from the bottom. Positioning the upper clamp too high or too low can significantly increase the potential for structural failure. Shakespeare pioneered low angle techniques in marine antennas in the 1960s and built them into many models. Low angle minimizes fading while maximizing range even during excessive boat roll in turbulent seas. A normal angle shortens the range and wastes power.

Cable

A ng le ke s pea re L ow RG-58 cable is sufficient for cable runs up to 20'. For runs over 20', larger and better, low loss RG-8/X, RG-8A/U or RG-213 are preferable. Shakespeare uses Low loss, UV stable RG-8/X throughout its Galaxy antenna line. Today’s enhanced cellular services, which operate in the 1800-1900MHz range, place even more importance on using a high quality caox. That’s why Shakespeare developed its exclusive Lo-Max® cable for dual band cellular antennas. Its low loss characteristics are near those of larger RG-8A/U and RG-213 cables, without the extra bulk and rigidity. For optimum performance from your MARINE VHF, HF/SSB and cellular communications systems, the cable should be kept as short as possible.
Sha Caution: cable supplied with some antennas may not be cut or altered. Be sure to check the instruction sheet before attempting to shorten the cable.

A FINAL WORD

The greatest tip to keep in mind is that no matter how much you pay for your radio, its performance will be directly proportional to the quality and performance capabilities of the antenna. Don't compromise...insist on genuine Shakespeare.
