The RF current travelling inside the cable shield, protruding outside the screen and descend toward the choke coil where the high impedance stop it (in fact, it's equivalent to a centre-fed dipole).\u003c\/h2\u003e\n\u003ch2\u003eWhy Gain-Masterhas better performance compared to a conventional 5\/8‚The new design of radiant element (Patent Pending) behaves as a centre-fed dipole, hence all RF currents are in phase. This arrangement allowed us to increase the maximum gain of 0.6dB in comparison to a conventional 5\/8‚ antenna with equal length; also it allowed us to have a radiation pattern similar to a dipole which has its maximum gain on the horizon.Gain-Master has the highest available gain for 5\/8, antenna and due to its angle of radiation perfectly horizontal, can improve performance, better than competing antennas, at least 1-2dB, corresponding to 26%-58% more gain, as shown by direct pattern comparison. Other Gain-Master advantages are:It does not require ground plane radials because it is a balanced antenna that function as a centre-fed dipole.It's protected against static discharge by DC-short.Thanks to it's cable coil (RF-Choke) at the base, Gain-Master is fully decoupled from its supporting structure (poles, towers, etc.) with the benefit of preserving both the impedance that the radiation pattern.It has a exceptionally bandwidth (see Fig.8) of over 4.5MHz (400 CB channels) from 25.5 to 30MHz and does not requires any tuning. It accepts a maximum continuous power of 500 Watts RMS.\u003c\/h2\u003e","brand":"vendor-unknown","offers":[{"title":"Default Title","offer_id":28736608698432,"sku":"3799","price":159.5,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0223\/4803\/8208\/products\/sirio_gainmaster_2.jpg?v=1558457815"},{"product_id":"sirio-gpa-27-45-27-to-45-mhz","title":"Sirio GPA 27-45 27 to 45 MHz","description":"\u003ch2\u003e\u003cstrong\u003eSirio GPA 27-45 27 to 45 MHz\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures: - CB Base station antenna - Unity-gain, Omnidirectional - Low radiation angle for excellent DX - High power handling capability - Made of aluminium alloy 6063 T-832 - Tunable by whips length adjusting - Side mast mounting allowed by optional bracket FT-2 code 2510004.00 Electrical Data - Type: 1\/4Œ«í‚ ground plane \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eFrequency range: tunable from 27 to 45 MHz - Impedance: 50Œ«íÖ - Radiation (H-plane): 360ŒçíÊ omnidirectional \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003ePolarization: linear vertical \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eGain: 0 dBd, 2.15 dBi \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eBandwidth @ SWR  2: Œçí€ 2500 KHz (230 channel) @ 27 MHz - SWR @ res. \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003efreq.: Œçí‰ 1.2\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eMax. power: 1000 Watts (CW) continuous 3000 Watts (CW) short time \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\n\u003cstrong\u003eFeed system \/ position: direct \/ \u003c\/strong\u003ecentre\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eConnector: UHF-female Mechanical Data \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eMaterials: Aluminium, Chromed brass, Nylon \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003e Wind load \/ resistance: 126 N at 150 Km\/h \/ 130 Km\/h \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eWind surface: 0.11 \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eHeight (approx.): 4730 mm \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eWeight (approx.): 1250 gr \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eRadial length (approx.): 2680 mm \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003e Mounting mast:  35-40 mm\u003c\/strong\u003e\u003c\/h2\u003e","brand":"vendor-unknown","offers":[{"title":"Default Title","offer_id":28736679542848,"sku":"Sirio GPA 27-45 27 to 45 MHz","price":44.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0223\/4803\/8208\/products\/1311935985_original_1.jpg?v=1558458205"},{"product_id":"sirio-2016-base-cb-radio-antenna-10m-11m-12m","title":"SIRIO 2016 CB 5\/8 WAVE Base Radio Antenna 10m 11m 12m","description":"\u003ch2\u003eSIRIO 2016 CB 5\/8 WAVE Base Radio Antenna 10m 11m 12m\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures: \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eCB Base station antenna, Omnidirectional High power handling capability Low radiation angle for excellent DX Coil protected by transparent cover Whip equipped with waterproof jointing sleeve Equipped with excellent multi element ground plane Protection from static discharges DC-Ground Made of aluminium alloy 6063 T-832 Electrical Data Type: 5\/8 ground plane \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003eFrequency range: tuneable from 26.4 to 28.2 MHz or 10 - 20 with ATU\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eImpedance: 50 Radiation (H-plane): 360 omnidirectional Polarization: linear vertical \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eGain: 1.3 dBd, 3.45 dBi \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eBandwidth @ SWR í‰ 2: SIRIO 2016 : í€ 2100 KHz SWR @ res. freq.: 1.1 \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eMax. power: 1000 Watts (CW) continuous 3000 Watts (CW) short time Feed system \/ position: \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eTransformer DC-ground \/ base \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eConnector: UHF-female Mechanical Data Materials: Aluminium Wind load \/ resistance: 166 N at 150 Km\/h \/ 130 Km\/h \u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cstrong\u003eWind surface: 0.14 mí‡ Height (approx.): 6100 mm Weight (approx.): 5300 gr Radial length (approx.
