Rain Gutter Antenna with SG 2. Second Article on the Rain Gutter Antenna. A couple of years ago I had written an article on the use of my rain gutter on my home as my HF antenna. This is the antenna I have been relegated to use for my HF operating due to the oppressive rules of the local Home Owners Association regarding external antennas. Although, I did remind them that it was now illegal to ban small satellite dishes and yagis for TV reception per the FCC, so they amended that clause in the HOA covenants but still continue their ban on any outside ham antennas. Ill not complain, as I knew what the HOA rules were when I got this house and have accepted them as a challenge to my ingenuity. In my original article I told about the inspiration I had to then use the aluminum rain gutters on part of the east side of my new house as my antenna. They measure 2. 5 feet vertically and then run 3. L or Marconi antenna configuration. In that article I also explained how I had planted a radial system beneath the lawn that consists of ten random length radials and how Ive also tied into this radial system the three aluminum window wells that are on that side of the house. According to accepted theory, the more metal and wire you use in your radial system, the better. You should consider connecting to your radial system any nearby chain link fencing, metal lawn sprinkler piping, fire department stand pipes, underground storage tanks, metal drain culverts, railroad tracks, etc. Download Free Hallelujah Chorus By Quincy Jones here. One of the drawbacks Ive noticed on my original rain gutter antenna was that it was somewhat tricky to load on some of the bands using a conventional antenna transmatch.

Rain Gutter Antenna with SG230 41 Countries in 5 Hours with 100 Watts into a Rain Gutter by Jack Ciaccia, WMG. I decided to try the ARRL International CW DX. No doubt that it would work Ultimately though, I had decided on using a different approach. I had read a lot about the SGC 2. Smartuner antenna coupler in ham magazines and on the Internet. It seemed like a plausible solution to this problem if it would work as advertised. The automatic antenna coupler is designed for use with end fed unbalanced antennas such as whips and long wires. It can be configured to be used with dipoles and inverted vees as well. This automatically tunable antenna coupler is an ideal solution for this type of installation due to the fact that the rain gutter looks like a non resonant end fed unbalanced antenna. What is the difference between an antenna coupler and an antenna tuner According to the SGC manual, Antenna couplers are placed at the antenna and match conditions of the antenna to the feed line in a very precise manner. Antenna tuners, on the other hand, are generally located at the transmitter output at the radio end of the coaxial feed line. Furthermore, antenna tuners placed at the transmitter allow substantial losses in feed lines to be corrected in order to fool a transmitter into working correctly. The losses are dissipated through heat or to ground. A coupler installed at the antenna eliminates these losses by providing a proper match of the antenna to the feed line. Sg Series Ups Manual' title='Sg Series Ups Manual' />The SGC 2. Smartuner is a true antenna coupler. After purchasing the unit from my local Denver HRO store I couldnt wait to get it installed. Fair Game 1995 Torrent. Upon physical inspection of the unit, I was impressed by the ruggedness of the construction of the SGC 2. This hermetically sealed antenna coupler was obviously meant to be installed outdoors and was even suitable for installation on shipboard. Included in the equally formidable packaging box was an impressive and informative 8. SGC 2. 30 with illustrations. SGC builds other models of these type of antenna coupling devices but the SGC 2. Smartuner is the only model that is rated at 2. W input. I probably wouldnt ever run that much power, but it is comforting to know that you are not running on the hairy edge of the limits of its power capabilities. Hopefully, that additional margin will translate into many extra years of trouble free operation. The installation was a snap. SGC gives you an additional quick installation guide for those of us that dont like to read the whole manual that was easy to follow. First, I mounted the antenna coupler as close as possible to the feedpoint of the rain gutter per the specification in the installation guide. This is because any portion of the feed wire that is connected to the SGC 2. So I mounted my unit on the inside wall of the foundation of my basement just above the wooden base plate and below the flooring. This location was just opposite the downspout of the rain gutter, which is my antenna feed point on the outside. A distance of about 8 inches away. I drilled two holes just larger than the O. D. of the intended feed thru wires through the 2 x 1. Then I took apart a piece of RG 8. X coax and separated the inner conductor from the braided shield. The inner conductor would serve nicely as the feed wire from the coupler to the downspout. You are cautioned in the instructions not to use coax to hookup these auto couplers on the antenna feed side. The now separated braided shielding served as the hookup to the outside radial wires and was then connected to the ground lug provided on the SGC 2. Now all that was left was to connect the 5. SGC 2. 30. There is a set of control wires and voltage wires included in this coaxial cable harness. The 1. 2V hot wire and ground went to my 1. V power supply. There are control signal leads that are also provided that are used for an indication of the couplers tuning. An LED antenna tuned indicator was connected between 1. V and the control signal wire. When the antenna coupler has found a match, the coupler drives the signal to ground on the control wire, which causes the LED to light. It provides a good visual indicator close to my operating position because I cant hear the quiet auto coupler relays engaging from my operating position. The total time for installation, from getting the unit out of the box to starting the initial testing, was under 4. To me, the proof of the pudding would be how well it performed in on the air tests. First I tried to load up the antenna on all the bands from 1. No problem whatsoever. Most bands indicated a 1 1 SWR and initial tuning time was from 3 4 seconds for finding a match. The Smartuner automatically evaluates and switches 6. Once it does find a match, the SGC 2. LC combination in its non volatile computer memory so that the next time you tune up on that same frequency it is tuned almost instantaneously less than 1. Now for the band I hadnt been able to get a match on before 1. I went down to the CW portion, where I usually operate, and it found a match within 4 seconds. Life is good again I also have not noticed any hunting by the SGC antenna coupler once it is tuned to a frequency. I decided I would wait until the evening to perform some on the air experiments with some people I knew on 7. SSB. I checked into the GERATOL Net on 3. MHz, which is a WAS net for the extra class ham. I have been active on this WAS net for over 1.
