This probably isn't the proper reflector to post this - maybe someone could suggest a more appropriate place... I have a 5 meter parabolic reflector antenna I'm in the process of disassembling, and w
I live in a city, I won't mention the name (Sunnyvale), where they have a whole staff of Nazis to harass citizens just like you're experiencing. Except in my city, they take color pictures, and provi
Okay, it's the wrong expression - I won't use it again. I don't know the name for a group that encourages people to report their neighbors to the state anonymously... Using the term for things other
Hmmm, my VSWR came up a little high this afternoon, see my QRZ page to see why. Actually, I shouldn't joke about it - I'm totally devastated. 73 all, -Doug Ronald, W6DSR _____________________________
Aware that the hoisting cable could break, or the winch fail, or some other unforeseen event could happen, I made sure no people or animals were in the fall zone. My expensive mistake was not torquei
Wind is the reason. I get usually two storms in the winter with BIG winds. My anemometer at about 20 feet has had the cups blown off it with a 116 MPH reading. Even this military antenna with a 120 M
SO2R is still feasible with the proper diplexer as long as the two operators can work stations in the same direction. This antenna's beamwidth is 70 degrees, so there is plenty of leeway geographical
I would like to talk to you about that vane idea when I get further along on the repair of this LP. Those back 4 elements are really heavy, so placing the boom-to-mast mounting plate in the physical
People would show up at every hearing, and there were four hearings, and say things like: "I don't want ANYTHING manmade in my view shed!". Another couple some 2.5 miles away line-of-sight, would sho
I think the heater type Jim is referring to is an infra-red radiation heater. They are not designed to work efficiently via conduction, or convection. I have one also sold by Costco, and put on displ
Using Street View, the tower looks pretty solid at the base, little rust, but all the bolts are intact. Based on the QSL card, I tried to find the 2nd tower's foundation in Google Earth and in Street

I'll put in a plug for the Axis Q6128E. I have one on my tower at a remote location, and can steer it around from my smartphone or any Internet connected computer throughout the world. The camera har

I have a question for the group (maybe not the right group): My log periodic dipole array antenna has the coaxial transmission line terminus with a Z0 of about 64 Ohms (measured with a VNA, and calcu
Nope. Not a chance. It's a commercial antenna, hundreds sold, and apparently they all work. I put a photo of the front end of the antenna on my website on a related page. The image is the first one a
It seems like a Maxim MAX16171 would fit the bill. It handles an input protection range of -42 through +76 V, and with an external FET, any reasonable current you need. I didn't look into an applicat
I've had for sale for some time a pile of Bird Termaline Model 8141 250 Watt continuous dissipation dummy loads. Anyone could make a 4-way combiner, and with 4 of these loads, reach 1 kW continuous.

My commercial 80 foot tower with a log periodic on a mast 20 feet above the tower top has sections of steel wire rope spaced 8', 10', 10', 10', then 70' to the ground turnbuckles. The antenna itself
