Build a 2.4GHz Co-linear antenna (for Wireless Access Points) The instructions are here at Easy Homemade 2.4Ghz Omni Antenna. Updated on: July 2014. This document describes the Cisco Aironet AIR-ANT2547V-N Dual-Band Omnidirectional Antenna and provides instructions for mounting it. How a Waveguide Antenna Works. A waveguide is a very low loss transmission line. It allows us to propagate signals to a number of smaller antennas (slots). WLAN ANTENNE Wi. Fi ANTENNE WIMAX ANTENNE DECT ANTENNE DVB T RICHT ANTENNE RFEXPLORER SPECTRUM ANALYZER1. MHz - 6 GHz FREQUENTIE ANALYZERRF Explorer is a handheld digital spectrum analyzer, a very affordable tool for work in all popular frequency bands. It is based on a highly integrated frequency synthesizer and double balanced mixer which offers high performance, compact size, low consumption and low cost. It has been designed to be used equally well outdoor and indoor, and can be connected to a PC for extra functionality using standard mini- USB 2. This model includes a 6. G baseline unit plus an RFEMWSUB3. G Expansion Module conveniently assembled and tested. It comes with two SMA connectors and three antennas: a nice Nagoya NA7. Sub- GHz frequencies, a rubber duck 5. GHz and a whip helical for 2. GHz band. Additional, specific band antennas may be needed to cover efficiently some of the frequencies supported. The combination of these two models offer coverage for most used communication frequency range used in modern communication technologies including Wi. Fi, Bluetooth, Wireless Audio and Video, LTE, GSM, GPRS, Satellite, CATV, DTV, etc. FUNCTIE OVERZICHT- Pocket size and light weight- Solid aluminum metal case- Includes a transport EVA carry case for RF Explorer- Spectrum Analyzer mode with Peak Max and Hold, Normal, Overwrite Averaging- Lifetime free firmware upgrades available, - open to community requested features- High capacity Lipo for 1.

One of the members commented to me that I. While it is not always feasible to home- brew a. This article describes a collinear antenna made from. RG5. 8/U coaxial cable and encased in PVC pipe. Before we start building we need. For RG5. 8/U coax it is typically . This. means that when we calculate the length of . Simply put, RF slows down by the velocity. All that aside now. First cut back. 4 millimeters of the outer jacket, braid and dielectric exposing. Figure 2. Now cut back the outer. It is best to lightly tin the braid with. Now solder each half wavelength as shown in. Figure 1. Attach a few feet of RG5. U to the bottom of the array. Figure 1 for feeding the antenna. Now its time to add the additional. First add. a . The length of the . If copper is used, it is. The length of the tube is calculated as follows. Slide three FT5. 0- 4. Figure 3. The toroids should be placed about . Use the same formula for. If you prefer, apply RF. SWR is found. Tape the toroids to the proper point. After completing the basic. RF. with the antenna on the floor or ground. Relatively low SWR. The SWR will be much lower once. If the SWR is greater than 2. It will be necessary to correct the problem. After good SWR is obtained, place heat shrink. For final mounting, attach the. It may not be possible to obtain a wooden dowel for the. Carefully insert the coax and dowel assembly into. Because of. the tie wraps, it is not necessary to use spacers but may be. Drill a hole for the. PVC. Do not cement end caps until the SWR has been doubled. Cement end caps and water proof coax opening on the. Use whatever type of coaxial connector is desired on the. RG5. 8/U for your complete. Use a low loss coax such as RG8/U for the main feed. Don't forget to water proof all coax. If the eight . If. B gain is still not enough for you then increase the number of. You will probably need to. Although only a 7. CM antenna. was described in this article, the formulas can be easily. After installing one of. DE N1. HFXBack to Projects.
