Steve, This is really helpful. One point of clarification: now that the 12V is not traversing the coax, what power source are you using? Solar panel + battery, or other? 73, David G3WGN M6O -Original Message- From: VE6WZ Steve Sent: Saturday, April 1, 2023 12:35 AM To: Frank W3LPL

Topband: Looking for user experience: DXEngineering Thunderbolt 160m vertical

2020-12-05 Thread David Aslin G3WGN
I'm building a contest station and the time has come to make a choice of 160m TX antenna. Looking at DXE Thunderbolt I note that the capacity hat extends to a significant distance down the vertical section. It's my understanding that will shield some of the radiation from the upper part of the

Indeed they do Mike. I ordered a set last month, it arrived last week. But the combiner isn't to Steve's innovative design. I'm using Steve's high impedance amp design for my build plus the PI4CC combiner and switchbox boards. Now Steve has put the cat among the pigeons with his new combiner

Hi all, Coming late to the YCCC array. Does anyone have a source for PCB or complete unit for the phase combiner/controller and switch box? Or anyone considering selling a working unit? Ideally shipped to UK, but can pick up at Dayton or have mailed to a US address. 73, David G3WGN M6O

Vic, sounds like you have what you need for your open wire line support, so this is an FYI: In the UK WD1A is called D10 field telephone cable. It's getting harder to find surplus, but is still made by Lacey: http://www.klaceycables.co.uk/shop/product/12/d10-field-telephone-cable The steel

Tim, This has probably already been said several times: this should be a DXE product! It would be a squeeze, but would just fit into my antenna field... 73, David G3WGN M6O -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of

Re: Topband: Wind Farming

I live in one of the areas of G-land with the highest concentration of wind farms. What I learned while looking for a new low-noise QTH: - small wind generators (50kW or less) have induction generators and therefore are essentially no-noise on HF & VHF. - mid-size (up to around 1MW) usually have
