End Fed Half Wave Antenna Kit

The Mosquitos EFHW antenna is currently being used by many HAMs. We decided to give a more hands-on experience to those who wants to build their own antenna. Here is our DIY Kit, same good antenna waiting to be build by you! You will find the step by step documents below as pdf file.

The Mosquitos Antenna’s End Fed Half Wave antenna is designed and built for the Portable Operators, the POTA Community, the Emergency Communications Operators, and well, just for those that like the Great Outdoors. With its relatively small size, it can fit in even the smallest pockets of your radio Go-Bags, Yet can be one of your most effective antennas. It can be easily deployable in different configurations. It’s been Field Tested by our POTA, and Portable Operator enthusiasts. And built with quality material. From the stainless steel hardware, to the reputable companies that we source our toroids from. Down to the wire that we source from Sotabeams in the UK. An absolutely incredible product from a great company. 

Our Products are hand made right here in the Good Old USA by Active Portable Ham Radio Operators. It’s great for QRP and the Power Hungry 100 watt radios that many Hams bring out in the field. An Absolute Must Have for Field Day, POTA, EmComm, ARES, RACES, Camping, or just some Radio Time. We supply an ample 68 feet of wire so that you can trim down to your best settings.  Its Power Rating is 110w PEP SSB, 50w CW, and about 25-30w Digital. It is built on a Winder for packing convenience. And has a 49:1 unun transformer matching unit built right on it. This brings the impedance down from 4,000 or 5,000 ohms, down to the 50 ohms our radios just Love to See.  It also comes with two different connectors.  An SO239 and a Female BNC.  So please choose the one that best suits your setup. 

This Mosquitos Antenna EFHW antenna is resonant on 40 through 10 meters. No tuner needed. It can be deployed in many configurations. From a Sloper, to an Inverted V, or L. Use your favorite way of launching it in a tree with the provided carabiner on top as the insulator. 

We’ve designed and tested this antenna with the perimeters described above.  Any alterations or over power usage that exceeds what is described in this informational flyer may damage the antenna, and or, any equipment that you have connected to it and by doing so, you do at your own risk.  We therefore are not at fault for any damages brought on by negligent use of our product.  

We’re making these products because of our love for the radio hobby and our dedication to the Ham Community.  Especially the Portable Operators.  We hope that you enjoy our antennas and tell your friends.  Get out there, and enjoy the hobby!
