Delightful observation on both points! It *could* make for a very intersting (and possibly quite effective) antenna,and it *could* make for a world of grief in airports! Shazam!

Tony I have experience with interesting equipment at airports- my 7030+ is set up as an "ultimate portable", and the X ray machine shows a cabinet within a cabinet, and a passle of battery packs and related circuitry jammed inside the larger cabinet. Whatever antenna I'm bringing goes in the suitcase, but I keep a short antenna with the radio so I can demo it for them. |
It is better if you're in a cabin in the woods. It's not better if you're in a hotel room, though. Tony Ah! quite true.. In hotel rooms,( or the hotel rooms I've been in ) I've found wrapping wire in a spiral round a 1 liter plastic bottle & setting it on the windowsill, then leading the signal over to the radio helps; - When venturing into airports, remember that your luggage will be searched * thoroughly *, and the batteries taken out of All electronic devices.. So anything in Memory Goes away Since this, I just write 'em down or travel with a copy of M.T. Dan |
You just made yourself the equivalent of a Hamstick. There's some
frequency out there at which it's going to work like gangbusters! At that frequency it should outperform your other antennas. But as you get away from that frequency, whatever it is, it will be worse than a straight wire antenna. /Carl Al Arduengo wrote: I just completed an atempt at construction of the "broomstick" antenna the plans for which were found on the internet. I used a 84" x 1.5" pole, a 14" aluminum pie pan, approximately 100" of 14/2 solid household wire. I followed the instructions as closely as possible in the construction. To my dismay the contraption provided absolutely *no* increase in signal strength that I could discern. Before I call this a flop I wanted to ask a few questions of the group: 1. Has anyone else built one and found it to work? 2. Does it really matter if the wire turns are actually touching each other or can the be spread by up to 0.5"? 3. As much as I hate to show my lack of antenna theory knowledge, does the type of wire covering matter? The instructions said to use 16 PVC covered wire but I could not find this description on the available wire at my Home Depot. 4. I made contact with the wore to the aluminum disk by stripping 1" of the end and wrapping it round a nail between the pan and the end of the stick such that when the nail was driven in it pressed the disk against the bare conductor. Is this valid? 5. Does it actually matter if the feed line is connected to the whip or the external antenna jack of the receiver? 6. How much wire should I use ideally? As much as I can fit on the pole? Enough for a quarter wave at 5MHz? 7. I have to assume that the benefit of this sort of antenna must be only nominal since if it worked as well as a stright wire, it would be more widely used. How much of an increase in received signal strength should I expect? It took me the better part of a day to gather the supplies and construct it so I hesitate to let the project go until I hear from experienced users that it is not worth it. I welcome any suggestions or critique. Best, -Al A. |
I have a broomstick up in my attic feeding a dx394 in the basement. It works
OK, much better than the 20ft of wire on the whip (inside). Got a 100' wire antenna Im going to put up this spring. |

( A piece of Copper Pipe. ) The better arangement would be to take a piece of PVC Pipe with a "T" on Top. Start with a piece of wire, and have a single loading coil wound for a specific frequency; and then run the wire up to the "T" and through it and out horizontally for as many feet as you can run the wire. Indoors - Stick the PVC Pipe in the corner of a room and have the top wire circle the room at near the ceiling level. Simply - A Folded Inverted "L" Antenna with a Loading Coil designed for a single target Shortwave Band. If this is then your thing - The 'build' a series of them if you need coverage on more bands. iane ~ RHF .. |

I welcome any suggestions or critique. It's not worth it. Lousy antenna. I have one out on my patio waiting for me to reclaim the wire off it. A 20 foot longwire out performs it. DnB, That's why they sell those small 23 Foot Roll-Up Antennas that can Clip to the WHip Antennas of most AM/FM/SW Radios. What Works... WORKS ! iane ~ RHF .. |
