This core is helically wound with copper wire and it is tuned to various band &#8220;tap&#8221; points. The KPO HVT Antenna is a shortened HI-Q design and therefore it has a narrow SWR bandwidth, particularly on 80 meters.  When measuring SWR adjust the SWR meter slowly across the band&#8230; no more than 5 kilohertz at a time.  Otherwise, you may miss the resonant spot. The HVT series antennas are intended for mobile installations; however, it is often used as a fixed base station or portable antenna. Trunk lip mount is recommended.<br \/>\nFor back packing (QRP) the antenna disassembles in two section, the coil section which measures 18-inches long and the whip (stinger) which measures 36-inches long. HVT400B is an ideal &#8220;stationary mobile antenna&#8221; and for vacation and field day QTH&#8217;s. <\/p>\n<p>Specifications:<br \/>\nPolarization: Vertical<br \/>\nFrequency range: 3.75 \/ 7.15 \/ 14.2 \/ 21.2 \/ 29 \/ 52 \/ 145 (146) \/ 435 or 445 MHz<br \/>\nTransmit: 80 \/ 40 \/ 20 \/ 15 \/ 10 \/ 6 \/ 2m &amp; 70cm<br \/>\nImpedance: 50 Ohms<br \/>\nMaximum continuous power: 120 Watts<br \/>\nConnector: PL-259 (Requires SO-239 Mount and Cable)<br \/>\nLength approx. 176.5cm (varies depending on the frequency band)<br \/>\nRetractable telescopic whip for best TX\/RX<br \/>\nWeight = +\/- 485 gram<br \/>\nFrequency Range: 3.75 MHz (80M) &#8211; No Jumper<br \/>\nFrequency Range: 7.15 MHz (40M) &#8211; Jump P1 to P2<br \/>\nFrequency Range: 14.2 MHz (20M) &#8211; Jump P1 to P3<br \/>\nFrequency Range: 21.2 MHz (15M) &#8211; Jump P1 to P4<br \/>\nFrequency Range: 29.0 MHz (10M) &#8211; Jump P1 to P5<br \/>\nFrequency Range: 52.0 MHz (6M)   &#8211; Jump P1 to P6<br \/>\nFrequency Range: 145.0 MHz (2M) &#8211; Jump P1 to P6<br \/>\nFrequency Range: 435 MHz (70cM) &#8211; Jump P1 to P6<br \/>\nFrequency Range: 118-136 MHz (Air Band) &#8211; Jump P1 to P6<\/p>\n","protected":false},"excerpt":{"rendered":"<p>HVT-400B: HVT Series mobile antennas are constructed of a rigid fiberglass core.
