Antennas, Feedlines, Towers & Rotors
/////////////////////////////////////////// Super simple Posted: 23 Feb 2017 01:00 AM PST http://forums.qrz.com/index.php?thre...simple.556546/ I have finally stepped out to HF with an IC735. I have the radio and a power supply but no antenna. I would like to build an antenna that is "compact" and easy to set up. Have been looking at different designs but I think I am just confusing myself so any help to get out on the air would be appreciated. Also would a tuner be a good suggestion? /////////////////////////////////////////// Building an Inverted L. Need some help.

I am interested in a purchasing a Vertical Antenna that covers 80,40,20,15,10 and 6 M bands. I live in a condo building directly on the Ocean here in S. Florida. The building is 20 stories high, on the roof of the building there is what is called a Mechanical Building. The Mechanical Building is part of the elevator shaft and stores mechanical equipment such as A/C compressors. The Condo Building Board has approved my request for an Antenna, but there are two stipulations.....

Legal Limit TX + RX. Obviously more antennas are planned; so perhaps some kind kind of selector type multiplexer is ideal. Like I could connect Rig A to Antenna A or B, and Rig B to the other antenna, transmitting and receiving on both rigs. (Obviously not the same antenna with two rigs at the same time.) I have two HF rigs, one (with more to come) antenna, one linear amp (which could just work with one rig if required, but...

Posted: 22 Feb 2017 02:41 PM PST http://forums.qrz.com/index.php?thre...esigns.555410/ I have an oddball hobby that involves setting up a wifi mesh network at a event a few times a year. My 2.4/5ghz routers do pretty well in most areas, but too many hops and bandwidth goes south, and there are several large areas isolated by trees that have poor connectivity to each other. Last year I played with some 900mhz gear as a backhaul, and it did a good job getting through the trees. But pointing the two flat panels at each other in a short amount of time can be a pain, and this... 902-928mhz H and V pol omni designs? /////////////////////////////////////////// Alex Loop - Mounting on a Tripod? Posted: 22 Feb 2017 01:52 PM PST http://forums.qrz.com/index.php?thre...tripod.556423/ Im contemplating an Alex Loop (along with a couple of end-fed wire antennas) to go with my new Elecraft KX3. I see that many Alex Loop users are buying a cheap tripod upon which to mount it. Can someone clue me in on how the antenna would mount to a tripod? Looking at pictures, I dont see anything on the Alex Loop which would correspond to the typical 1/4" x 20 screw that most tripod heads come with. As a photographer, Ive got a small, light carbon-fiber tripod that I normally carry... Alex Loop - Mounting on a Tripod? |
