Has anyone bought one of these and has it working? Not cheap but still well under the AIM 4170 and I dont need response to 180 MHz or a dual detector option......yet....but Im making plans for this y
Make them shorter and they will often do well over tidal marshes but not over open water. For a 240' tower Id suggest gamma feeding it up at the 1/4 wave point and use 4 elevated radials. It the AM B
ON4UN and others suggest 15 meters I believe. Ive used 25-30' here and it does well with 5 2 wire Beverages with their ends and antenna grounds also spaced from each other by at least 30' and a few a
But arent you in the boonies Mike with little common mode noise? I notice a few others with lots of acerage do the same but when I was enroached upon on both sides I just followed ON4UN's lead. It wo
I only have a couple of those lamps and a bit of bypassing in the fixture knocked it down a lot. Since they are seldom on when Im at the radio its tolerable or I shut them off. The one problem I have
Another entry into the analyzer battle, the C model covers 530KHz to 230 MHz. http://www.mfjenterprises.com/MFJ-259C_Flyer.php I wonder why it didnt go down to 470 KHz which would include the coming
Nah, it will have to go to at least 136 KHz; the future Topband. Carl KM1H They'll be offering a 250 kHz to 500 kHZ version later, Carl, to sell ya! 600M
Im waiting for N6LF to add that to his review results. http://www.antennasbyn6lf.com/files/vna_comparisons.pdf Carl KM1H I had a look at the matching Rosenberger calibration standards and for the mon
Can HP microwave loads be used? I have a set good to 24 GHz and another to 50 GHz. Carl KM1H I'm a VERY happy owner of the 3E model VNWA. I've made measurements on my 160M antennas with no difficulty
SMA for the 24GHz, open, thru and short. I also have high end adaptors to N, APC, etc. There may even be an old type N cal kit from "back in the eighties" Carl KM1H -- Original Message -- From: "Char
I have the B&H microscope, stand, light, table, etc as well as a hot plate and access to a bonder when needed. Plus various knives, blades, scalpels, gold plated needle point iron, etc for fine tunin
So you can see better to stuff more wire in a binocular core. But I agree with Charlie that the principles are the same and it often may be easier to test an idea about a 160M antenna at say 10 or 6M
Not cheap but placing a heavy duty rope at about 12' can be a good shock absorber but the fact is that WD-11A is still fragile. It took me a few years to let Mother Nature drop most of the dead wood
All the TV splitters Ive taken apart are pure autotransformers with poor isolation. A VNA will show them deterioating and doing very little at 160M. It is simple enough to wind transformers for a spl
Is that any different than the traffic nets used on the hambands since the 20's or earlier? They were also accused of circumventing MaBell. If the communications are strictly personal then the emails
Im in the wrong business! Carl KM1H Have a look on ebay - rx splitter . http://www.ebay.com/itm/ANTENNA-SPLITTER-COMBINER-RX-HF-1-50-MHz-SO-239-conn ectors-/321217220222?pt=US_Radio_Comm_Antennas&has
Commscope owns Andrew, likely just a different name imprinted on the jacket. Carl KM1H You could also use that stuff to feed your TX antenna. I do here. If it's like the Commscope CATV F-6 coax I hav
Many have tested various grades of RG-6 shield integrity from HF to microwave in a lab enviroment. It does vary, even at HF and low VHF so I suggest sticking to a name brand and getting the best you
You mention keeping the highest impedance part "clean" electrically, which would make me think putting the small coil nearest the anteanna would be best. Whichever part of the inductor is shunted out
