I haven't looked, but I'm guessing that neither of the *mini* DIN series have much to choose from as far as connectors for 3/8" braided coax (RG213, LMR400, etc). They were developed to be the next g
Could you layout the typical matrix of connectors from the cell antenna down to what remains of the shed at the bottom.? 2G (GSM & TDM) used mostly simple N connector based transmission lines with t
For capturing screenshots, especially of tower & antenna related items, Greenshot has no serious competitor. -Steve K8LX If you don't want to use the Snipping Tool (standard on Win 7+) Greenshot is a
I use nothing but JMA's because my main customer specifies them. 4.3-10 JMA's for 1/2" corrugated, 1/2" Superflex, 7/8" corrugated, and 1-5/8" corrugated are widely available, but unfortunately JMA c
Not really, they're both rated for -165 dBc, or something like that. BUT, the 4.3-10 IS supposedly less dependent on accurate tightening with a torque wrench (during mating with the female connector)
On commercial towers we use a hoisting grip (one per cable) and a shackle (also one per cable) to support the dead weight of the cable, and appropriately sized snap-ins all the way down to keep the c
The "Spid" rotators (sold by AlfaRadio and Array Solutions in NA) are pretty skinny, except for the motor which would probably stick outside of your top section, but the motor is stationary so would
Bob, The idea for hard-wiring a short pigtail that comes out a hole on the bottom of the Ham4/T2X is a great one, which is why I've been doing that for decades :-) The legacy terminal strips on these
I'm trying to to figure out what was wrong or hard to understand about Jim's answer? I've seen many examples of poor quality cables with *RG213* stamped on them... -Steve K8LX Oh for Pete's sake Jim!
Isn't that "slipping" sort of a mechanical fuse. I was told not to drill a hole and put a pin through that mast to avoid slipping as it might break to rotor and/or the mast, I have used a exhaust cl
There has got to be more to this story. I have personal experience that Rohn 25, with a 2 element 40, and a TH6DXX at the top will self stand at 120' with three sets of guys, when one deadman is unh
As you note, there's a big difference between outdoor & indoor conditions. It's hard to beat clear heatshrink over your label of choice for outdoor use - IF you have the foresight to slide the heatsh
New to the Northeast, and all the critters that eat...well, everything when it gets cold enough. I am planning on running a length of FSJ-4 (1/2" Andrews superflex) from the house to the end of the b
I concur that the Superflex PVC is thin and would not be the best choice for long outdoor runs both on the tower or buried however I have been using FSJ4 for short outdoor jumpers for many years wit
OK, it's a terminology issue. There is: 1) Smoothwall hardline. 2) Spiral corrugated hardline (like FSJ4). 3) *ringed* (my term) corrugated hardline (like LDF4). FSJ4 is #2, and water will travel und
LMR400 works well as a rotator loop if you dress it in with a relatively large hanging loop. Some setups aren't conducive to such a loop (i.e. top set of guys right at the top of the tower, etc). I a
Martin, Many years ago I was faced with a similar situation with my medium sized Telrex rotator. After much thought I came up with a solution using a mostly gutted HyGain Ham4 rotator (mounted under
Well here's the advantage of captivated center pins: the pin is NOT bonded to the center conductor. IOW, if the coax center conductor shrinks a bit, it can slide in the center pin and the pin stays p
Oops, wrong group. But may be relevant here as well. And that's exactly what you want it to do - especially with an N connector. -Steve K8LX Exactly my experience, even with captivated pins!! And my
For robustly securing (at a reasonable price) a smallish cylinder to a very large parallel cylinder it's hard to beat a chain mount, such as: https://www.sitepro1.com/store/cart.php?m=product_detail&
