The BN-86 is a transformer balun. Probably a little light if you plan on running anywhere the legal limit. Will saturate at higher power levels. Not for verticals. 73 ES DX, Gary -- AB9M I found one
With respect to your comment regarding: If the coax were run through a weather/UV resistant sleeve of sufficient diameter... I found Non-Metallic Conduit is able to accommodate a PL-259 and any RG-8
Rudy, I have a similar situation. My QTH is on a glacial moraine about a tenth of a mile from the crest. There is water bearing clay less than thirty inches down and the soil is the black muck left b

Agreed on the 9913..... I just took down some I had up over 25 years.... (bought a 500 foot spool) ... the copper was still bright and no moisture problems. I used a RG-214 solid dielectric cable as
I never found a good solution to roosting birds except turning the beam frequently to get the turkey buzzards to leave just as soon as they started using the TH-7 boom and driven element. 1 KW CW on
I've run several top loaded HF2Vs over two dozen 66 foot radials over water bearing clay and septic leach field the past 27 years at my current QTH. I chase DX on 160 - 80 - 40 and get good results (
I have 4 twelve foot wires as the Top Hat (umbrella) with weed trimmer line as the remainder for guy lines on my HF-2V. The top (40 meter) coil is completely collapsed and shorted out on my HF-2V usi
Mike, I forgot to say the top loading can give your HF-2V a low VSWR across the entire 40 M band or across the entire phone or CW portion.... great for contests! 73 ES DX, Gary -- AB9M --Original Mes

I've used Tri-Flow, WD-40, diesel fuel, automatic transmission fluid, Coca-cola, vegetable oil, olive oil, and acetone, separately and in some combinations for penetrating and freeing stuck parts. 73
Here's another MOV solution; http://www.arraysolutions.com/images/SurgeSupressorManual_1.pdf ..... simply (8 or 16) 65 volt MOVs in a NEMA box. I mounted the 16 terminal version at the ground window
Read the two different manuals, the control line protector has 65 volt MOVs, the COAX protector has the gas tube and inductor, both have caps if I'm recalling correctly... 73 ES DX, Gary -- AB9M On 1
John, one may be able to model a vertical and ground system, but the proof is in how it plays (or works) and that may be impacted more by soil and local conditions which are not modeled. Case in poin

Your controller probably has an offset like the HYGAIN DCU. RYFM and recalibrate the controller. First try the default calibration. If that does not work the offset is either 270 or 90 degrees. 73 ES
Another solution is a double throw relay operating NC to ground with NO power but open with power from the radio acc power jack. When closed the static build up is drained. OR use AS-302U or AS302N I
Yes 18, 14, and 12AVT antennas are DC grounded to help avoid static build-up and discharge into a radio or switching network. 73 ES DX, Gary -- AB9M I recently bought a very old 18AVT-WB which, after
A faster hole digging approach used locally is a 36 - 48 inch auger usually mounted on a skid-loader. If there are no sizable rocks its quick work. 73 ES DX, Gary -- AB9M If you are lucky your county
