wrote: Is this a suprising result? *I kinda thought the active antenna would outperform the wire. Sounds normal to me. The loop on the active antenna is very small. Not a heck of a lot for the preamp to work with. Will a tuned mutliband really be that much better? Not if you are just receiving. If you were going to make an antenna that's relatively easy to store and set up with the goal of getting some fun radio stations and a handfull of sideband stations what would you opt for? I use dipoles fed parallel from coax. But I transmit.. *I would define easy as raising a 30ft guyed mast as relatively easy. A 140 foot multiband wire antenna off that would be pushing the limits if not too much space. Would be overkill for receiving. And finally, will the reception of the ANLP1 increase very much if it's 30 feet up? Not for most signals. Only if they were line of sight. Thanks for your time helping out a rookie. *I'm slowly being sucked in! -- Bajamatic If you are receiving, you really don't even need a feedline for random wire antennas. So I'd just take a roll of wire and throw it up to match the site. Heck, take both of them if you have the room. But if I had to choose one, I'd take the wire. Even 50 feet should be plenty. And it doesn't have to be high off the ground either. I camp quite a bit, and have often transmitted with dipoles as low as five or so feet off the ground when I had no trees or tall supports. I've got a place out in the sticks, and I always have a radio there, but I have dipoles in the trees that I leave there. I run 80 and 40 dipoles on a single coax and the apex is up in an oak tree about 25 feet or so. I've got about 100 feet of RG-58, so it will pretty reach anywhere around the camp or driveway area. I usually stick the radio on a stone bench I have there and power it off the car. When I leave, I roll up the coax and hang it on a tree branch stump. This was about three weekends ago.. Weather net on 75m I stumbled across.. Scuse the camera focus hunting.. :/ http://home.comcast.net/~disk100/radio.wmv BTW.. the antenna is resonant 80/40, but I have no trouble receiving any other HF frequency. When I was there three weeks ago, all bands were open up to 10 meters and I had no trouble hearing any of them. Receiving is just not very critical. It even does OK on VHF.. I listen to the local sheriff dept, etc at night sometimes. I have no trouble hearing them on that HF antenna. I've got to where I use the radio more out there in the sticks than I do here at home.. :/ |
