    CB dipoles

    I will second that on Dipoles working good for local. My inverted V has given me very impressive performance on the local scene. It's not perfect and yes, I have noticed the polarization difference. But it still works

    Antenna analyzer

    I guess I have a soft spot for old tech. Though vacuum tubes were very quickly disappearing when I was still fairly young, I remember them fondly. In high school, I took electronics shop (my HS was the only one in the city of Milwaukee that had electronics) and at the very beginning, we went...

    Antenna analyzer

    Is there anyone on here that has ever used a noise bridge in the past for tuning antennas? Just curious.

    My inverted V

    I did the calculation for the midpoint of the frequency range, (27.165mHz) and added 2". the ends of my wires terminate in a loop help by a small screw, nut and two washers. Adjusting it consisted of simply loosening the nut and moving it up or down the wire. After 2 adjustments that totaled...

    My inverted V

    I had the feed point of my inverted V at 31' and got decent Rx and Tx in excess of 18 miles on AM. I first put it up without a BALUN and it worked just fine. However, I was getting a lot of radiation from the shielding of my coax. It made taking SWR measurements kind of difficult because my...

    My inverted V

    Another thing I have forgotten about! Giving a wire antenna a little "give" by either springs, or the counter-weight system you described. I guess I'm getting old

    My inverted V

    My only concern is the wind we deal with very often around here. This wind is compounded by the fact I live way out in the country on a farm, which equals a lot of flat land with no obstructions to mitigate the wind. In fact, I have thought a lot about putting up an electric generating wind mill...

    Antenna analyzer

    I am interested in getting an Antenna analyzer, but have a very limited budget. I saw a Chinese model on Ebay that was under $100 brand new, but after doing some research, it appears that this unit is, to put it mildly, less than stellar in reliability, or performance. I see very few used ones...

    My inverted V

    I made an inverted V dipole complete with home brew BALUN and it has been performing beyond my expectations. It was just an experimental antenna, but now I would like to mount it permanently because it just works great. Now my question is: presently it is made of stranded 16 AWG insulated wire...

    Antenna mast isolation

    Oh! You mean PEX water pipe. It also comes in red and white, if blue doesn't suit your fashion sense

    Sirio Boomerang A

    I recently saw a Sirio Boomerang antenna for the first time. Anyone know anything about these? I was just wondering what kind of performance it gets with only one radial.

    Noise Bridge

    Were you referring to a noise bridge or the MFJ 259 analyzer?

    Noise Bridge

    Anyone have or ever used a noise bridge? Since my budget is kind of small, I was thinking of one of these beauties instead of an antenna analyzer. Just wondering if anyone has any opinions on them.

    Communications Concepts

    I originally saw the schematic for this amp in a book named "Circuit Encyclopedia and Troubleshooting Guide." In the description, it said that " both the parts and kits for this amplifier are available from: Communications Concepts....." The copy write date for this book is 1993, so I was...

    Communications Concepts

    Anyone here ever hear of, or deal with Communications Concepts Inc. ? I was looking at one of their linears, namely the EB63A 140 watt. It is supposed to produce 140 watts with a freq response of 2-30 MHZ and can supposedly handle up to 5 watts of driving power. It will handle AM or SSB without...
