As I recall, about 9 years ago cable clamps were recommended for Phillystran sizes under 6,700#. I purchased the clamps, end cap and 6,700# Phylistran from Texas Towers around that time. I also purch
Polyphaser makes one. Does anyone know what device is used for Rotator Wire Protection and can it be purchased from Mouser or other electronic supply? Since it is a shunt device, it must be a leaded
I know I'm not answering your question, but here's what I did on my 15 and 20 meter stacks. I used equal lengths of RG-213 from the antenna to a point in between both antennas on the tower. I then ru
I ran a 4" PVC pipe into my house. I removed a few bricks with a hammer and chisel and drilled through the wood with a hole saw. I broke some of the bricks in half and replaced them to create a circl
I have many of these. There are two terminal blocks with four terminals each for a total of eight. You use this a terminal strip and connect two wires to each position. One wire goes to the rotor and
I have a DX Engineering 10DX-8 (8el, 10m, 48' boom) yagi. I'd like to convert it to their 10DX-7 (7el, 10m, 36' boom) antenna. If someone has a manual for the 10DX-7 I'd appreciate a copy of the page
Does anyone have any experience with the OWA design yagis. Is there any advantage other than low SWR and direct 50 ohm feed? I modeled the 15m 6el X 36' boom and compared it to my DX Engineering 15DX
Someone recently inquired about the ARRL insurance plan. I have a Yaesu FT1000MP Mark-V and a Kenwood TM-331 that were severely damaged my a lightning strike to one of my towers. The insurance has ag
I believe that the Corona tips were on the earlier versions. I purchased several of their antennas after 1988 and none had the tips. I have several Telrex antennas . but bought these DOWN and dis-ass
It appears that the relays used in the six-pack do not tolerate much lower than 12v. I had intermittent problems with mine, although my situation was much worse than yours. I used a Top Ten Band deco
I filled my legs with anchor cement. It's been fine for the last 13 years. John Lou, I,too, have a Universal tower. From previous experience with this tower, I had the steel legs that are in the conc
In the future, every compass on Earth may point south because the world's magnetic field could flip. However, researchers said there's no danger of airplanes, migrating sea turtles or other magnetism
I would not recommend the HDR300. I owned two of them for several years and they needed servicing many times. The biggest problem was that the shaft keyway would elongate and become very sloppy. The
If you have had no problems with your HDR-300 consider yourself very lucky. Many people responded directly to me with the details of their problems. I've owned two, one turned a 6el 20m beam and one
It could be made by many companies. I know Pyrod uses solid legs. Greetings all - I've been lurking here for a couple of weeks, and now have a question. I've just become the proud (well maybe) owner
They've unfortunately been out of business for a number of years. There's a DX Engineering in Ohio who sells some antenna hardware, but I don't know if he sells complete antennas or switches. John Do
They need to be close to the water. From ZF2JB I had a vertical 5' from the water with a reflector vertical in back. This worked very well. I think further than a wavelength away there's little if an
Crank up towers do collapse on occasion. Last month I had dinner in Aruba with P49MR and his tower cable broke twice in several years. I also know first hand of others in Illinois that had their cabl
I installed 140' of Rohn 65 with a crane. I put up the first 40' assembly and attached the guys, then the last 100' went up in one piece. The crane was only 120' so I couldn't attach it to top, which
