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

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...

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

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...

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...

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 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...

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...

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...

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

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.

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

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.

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...

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...

Hmm Looked again at them and the model is KL203P.. Is this the infamous P model Tall man was talking about? BTW, I'm not worried about over-driving the amp and blowing it out since I plan to hook it up to a stock, out of the box, Bearcat 980SSB.

Thanks for the info. I think I might just give one a try, like it was said, If it blows out, I'm not out much

I was recently looking at mobile linears for a CB on Ebay and saw a RM Italy brand. It's only a 100watt but was rather inexpensive. Has anyone heard of these? Are they any good?

Back in the early 90's I lived outside of Milwaukee WI. There was a night back then where you could see the aurora. I must have spent a couple hours outside that night viewing it. It was something to see.

what I read stated that there was a huge dark area. Basically like a massive sun spot, which I know is very good for ionizing the upper layers. But, on the negative side, they were saying that the aurora might be visible as far south as northern Missouri, which would suggest a CME. Hmm? BTW I'm...
