My next stop on the planning trail was to the Gap Antenna discussion group on Yahoo. I found on the net. It works but sometimes cant quite pick up and reach out. The following pictures are for help with assembly. There are drill holes on both ends. Take the remaining black jumper and attach it to the top of this rod with a screw and tighten.
Form these four into a cross perpendicular to the mast. You may want to coil a bit of chicken wire in the hole before pouring the cement. This restored full operation and in the following week, all continents were worked on numerous bands -- particularly 12 meters -- including Norfolk Island, San Andres, the Marshall Islands, Gambia, Zambia, and West Kiribati. Your Transceiver will soon let you know if things are not quite right! The drop shipped package arrived in only one week; I barely had time to think about the planning of a mount for it! I made the mistake of deciding early on to thread the yellow feed line out of the hole on the side of the antenna lower section. Naturally, if these metal objects are short you can get closer than 30'.
Heartworm - Irvine Vet Services Dog Dermatology Diagram - 1 The Flea Life Cycle Diagram: Flea life cycle diagram: This is a diagram of the flea lifecycle as it applies to the majority of flea species types. Likewise the shorter the length of the Counterpoise Hoop the higher the resonant frequency will be and the longer the Dacron rope will be. This won me the Rocky Mountain Division Unlimited Class plaque! How long did it take to assemble and erect the antenna? My experience leaves me curious if other well respected antennas shouldn't be given a try. Your email address will not be published. This is generally a result of the tower exhibiting a resonance for that frequency. Before starting assembly, check the various parts in the shipping container against the pictorial parts list in figure B to establish all parts are present.
I found out that there was a short between the center terminal and shell of the connector I had soldered onto the antenna. The only solution was to take the antenna down and cut off three feet of the mounting pipe. Likewise for putting it back up. The standoffs have been pre positioned at the factory for your convenience. Use of an antenna tuner is not required nor recommended. One common problem is the exit point for the yellow cable and connector at the bottom of the antenna.
Worse, the shack includes 3 Pentium servers of various types, a 100Mhz switched data network, and a 56kbs dedicated internet link. Click for pictures and text. The antenna is insulated from the mounting mast by plastic rings. Also, work alone during assembly. Trip number two was a couple days later. Titan's broad bandwidth and no tune feature make it an ideal antenna for getting those multipliers during contests or switching frequencies as band conditions change.
Seven months later it was finally time to put up a new antenna and the was once again the choice. After assembly, I took these photos to document the locations and had tech support view and verify that everything was correct. Each rod should be parallel to the Main mast. You will also need a small square or oblong rectangle of insulating material such as Perspex or Paxolin. Now locate the longest standoff on the upper cross assembly.

I have a picture of what I have if it helps. Then I have to decide on a permanent method for getting the cable into the house and making a proper station ground. Hi and tnx for some very informative photos. He has talked with the men at Gap many times and they have been very helpful.
Slide the end with the 4 standoffs over the coax tail protruding from the Main Section center insulator. Leave the standoffs as is for the moment. The broken wires were replaced with flexible Copperweld -- as were several other wires -- and the insulators repositioned and tightened as much as possible. This is the one that terminates that end of the black rope is tied to. The entire mount had to be lifted out of the pipe so as to take the antenna down. It is just barely under the limits.
He used a flagpole-like configuration. I have now adjusted the 40, 15, and 12 meter frequency coverage and the antenna meets all specifications. Insert 4 screws and tighten. The reason why this design gives such good results is because of this: At ten metres the 10M section acts as a half wave dipole but at the same time the 15M section also radiates some lobes and the 20M section acts as a full wave dipole on 10 metres in addition to the radiation from the actual 10M section. After it leave the hole is when you need to solder on your connector. Drawings are by hand and sparse. I cleaned it up and installed it only to find it didn't work.
Shouldn't matter as the 30 meter tuning was not a big problem. It does work fairly well and makes a great back-up antenna too so I'm keeping it. In my case, I had failed to tighten the standoffs sufficiently and they changed position, breaking some of the interconnecting wiring. Wiring color code or symbols, wiring harness, radio and audio wiring, circuit diagram, light switch wiring diagram. This made the drilling a breeze and all the holes lined up just right.
