The KISS-SSB is perfect for all fiberglass, wooden or even metal hull boats, both sailing vessels and motor vessels.

This simple grounding / counterpoise array is specifically designed for transmitting on all the common SSB channels and HF frequencies along with the long range ham frequencies, Sailmail, Winlink, and NOAA weather,  when used with a tuner.

All of these frequencies test to less than a 1.5 to 1 Standing Wave Reflection (SWR) with low power loss!
Not only is this easy to install, it just makes sense:

1 - No need to drill holes in the hull under the waterline for a "grounding plate"
2 - No need to run the copper foil everywhere.
3 - No need to bond all the thru-hulls.
4 - No maintenance keeping the underwater bronze  grounding plate  clean.
5 - No drag when sailing.
6 - Can even be used when your boat is on the hard and not in the water. Installation location is not dependent upon where the water line is. The KISS-SSB is it's own reflective counterpoise, that means you can install it anywhere within four feet of your tuner location.
7 - No need to constantly check all the copper foil connections for corrosion breaks.

It has been proven that HF frequencies do not penetrate more than two inches of saltwater, that is why submarines use very, very low frequencies at 15khz.  SSB / HF  frequencies are in the 3 to 30 mhz range. There you have it, the bronze ground plate is only effective if it is on the upper few inches of the water. This is not practical at all on the hull of a healing sailboat or motor boat. That is why metal hull boats always have such a great signal, they have a lot of surface water skin area.  It is the use of a copper radial system much like the principal that the KISS-SSB uses that works. We are seeing many metal hull boat owners use our KISS-SSB instead of their hull due to corrosion concerns. The main advantage of the KISS-SSB over using 100 square feet of copper foil is the fact that the KISS-SSB uses perfectly measured copper radial lengths to match the frequencies used for marine SSB, which means a better and stronger signal, a lot less RF interference, and it's simple to install and makes for a clean fast installation.

The proper name for a ground plane is "Counterpoise" if you study that name you will see that it is an opposite phase signal below the antenna to repel the high wattage signal off of the radiating antenna such as the backstay / whip / GAM. Thus the name "Counter" poise equals "opposite phase signal at a low wattage strength. This counterpoise signal needs to be below the radiating antenna and thus is simply closer to the ground or water, and this is why it is also called a "ground plane". The problem here is that so many people think of it as an "earth ground" when in fact it has nothing to do with earth ground, but simply is a low wattage opposite wave phase signal below the high wattage antenna of choice.

It is a proven law of physics that a radial cut to proper wave length will resonate with that particular frequency. The KISS-SSB uses many radials to resonate in all the marine SSB, Winlink, Sailmail, NOAA Weatherfax and all long range ham frequncies from 2mhz through 28mhz. All in one easy to install neat package, the KISS-SSB makes for the perfect counterpoise/ground plane on fiberglass or wood boats. Even metal boat owners use our KISS-SSB instead of their hull for corrosion concerns.

The KISS-SSB is a self-contained counterpoise radial counterpoise system that is the perfect answer for trouble free Marine SSB communications. The word "GROUND" could be the problem it should be "COUNTERPOISE" The system of using exact pre-measured counterpoise ground radials is even suggested in every Icom, SGC Smart Tuner, and Furuno Auto-Tuner manuals. Right now the most commonly used tuner is the Icom-AT-140 and if you look on page two you'll see the principals used in our KISS-SSB Ground Plane System.  Using the lifelines, engine, tanks and other metal is the most common cause of RF interference and static, and it can upset other electronics.

Land based radio stations with tall antennas all have radials of the frequency they are transmitting on around the base, or the guy wires or even buried in the ground. They only transmit on one frequency, so the radials are the same length, if they transmitted on many frequencies the radials would all be different lengths even though they all do connect to the same point. What makes our KISS-SSB work so well is the patented ability to put a lot of different length radials in one housing to match all the frequencies desired and not have one length trying to react to many different frequencies. Plus it puts it all in one easy package that is easy for the end user to install. Compared side by side with 100 feet of 3" fresh copper foil, and a bronze plate in the salt water outside of the boat the KISS-SSB works just as well. The advantage of the KISS-SSB is no maintenance, a lot less labor, no holes in the hull and costs a lot less. Plus after a couple of years the KISS-SSB will probably work a lot better than the deteriating copper foil and corroded bronze plate. There is a reason why the tuner manuals suggest measured radials, not one, but many, one length close to most bands used, and they all, even though different lengths, connect to the same terminal, not because they all act like one wire, but that there needs to be at least one close to a multiple of the wavelength of the frequency desired to transmit on. With this said, the KISS-SSB is in-itself a free standing reflective counterpoise and is not dependent at all on the water line or where it is installed in relationship to the water line. Nearly everyday we get orders from people that were referred to us from Icom, Furuno, Kenwood tech support staff.  In 2005 when Icom was having problems with the "clipping" on their M-802's we found that didn't happen with users of the KISS-SSB, and that is because of the low SWR and the ability for the RF signal to be radiated out into space and not reflected back at the radio from boats with poor ground plane and antenna systems.

There just is not a standard way the KISS-SSB has to be installed, we have seen, tested and heard of so many ways it has been impressive. However there is one rule of thumb, the KISS comes with a four foot lead that can’t be trimmed or lengthened as the four foot lead is an integral part of the length of all the radials enclosed within the tubular housing. With that being said the KISS will be within four feet of the tuner. Plus we all know that the tuner should be as close as possible to the radiating antenna such as the back stay, or a fiberglass whip antenna on a motor vessel. Now once the four foot lead is connected to the tuner each and every boat will be different, but the rule of thumb here is to stretch it all out, four foot lead and the ten foot tube as best as possible, however if there are restraints as there normally will be you can feel free to run it back and forth in the lazerett, or coiled no less than a three foot diameter.  It is not mandatory that the KISS be stretched out straight as it only sets up the inductance to resonate the signal off of the antenna. We have tested the KISS running down the middle of the bilge and even under the engine and the results were just fine, much to our surprise. We have heard of the KISS being run inside of a fiberglass arch above the wheel house on a large fishing vessel with good results. The most common installation of course would be in a lazerett or along the deck to hull joint just below the deck with nylon wire ties keeping the KISS secured out of your way. The KISS is often used by Ham operators with antenna restriction covenants that do not have an easy wire run to earth ground. They simply run a long wire in the attic and run the KISS underneath on the joists using an external tuner in the same location. We get a lot of questions from people that just do not understand that the HF frequencies (2-30mhz) require a two part antenna system. You must have an antenna (back stay, whip or GAM) and a ground plane/counterpoise such as the KISS-SSB is. The KISS-SSB is best described as "A tuned Counterpoise". The enclosed radials are cut to lengths to resonate the frequencies used by Marine SSB, Winlink/Sailmail, NOAA Weatherfax, Coast Guard.

In Technical Words:
The KISS-SSB simply acts as inductively loaded dipole elements in parallel with the tuner bringing the backstay element to resonance effectively making a loaded, off-set fed vertical dipole.
Using the coil loaded 1/4 waves so that there is a current max at the feed point hence maximum radiation and the only ground loss being the ohmic loss in the inductance of the coil.  By staggering the coils down the length of design there is also some capacitive loading from the non-resonant elements helping bandwidth and it obviates the issue of undesired resonances as well.
