No, "Reverse Thread" (not Lefthand Thread)

Yeah, looks like I will either end up cannabilizing the existing connector off the little whip or biting the bullet and buying the whole antenna assembly -- *assuming* I can get the range I want once I try this on the roof :<

From

"Other suppliers offering such universal kits include Bomar Interconnect Products and MegaPhase. To address the needs of technicians and engineers in the broadcast field, Bomar has readied a 42-piece adapter kit, called ADPT4RP, that contains the parts most often needed by technicians in on-site antenna installations. The product consists of two male and two female Type N, BNC, UHF, TNC, TNC reverse-thread (RT), TNC-RP, SMA, and SMA-RP 50-?

-------^^^^^^^^^^^^^^^^^^^

coaxial parts as well as eight universal adapters and two flat wrenches. These parts are fabricated using precision -machined brass with corrosion-resistant gold bodies, Teflon insulators, and gold-plated contacts. For its part, MegaPhase?s universal adapter kit includes tools to properly terminate three different-length cable sub-assemblies with various connector combinations."

If I can get the coverage I need *on* the roof, I will try moving things *inside* the 'ceiling' (flat roof) and do the test over to see what I've lost. If this works, then I can find a convenient place where things are close enough together that losses are minimized.

I can also use hefty cable since I am not going to be running hundreds of feet of it!

Cool! Learn something every day (it's still named wrong ;-).

Double silver shielded, with teflon dielectric? I have a couple rolls of it, in one of the shops. Then there is waveguide, for even lower loss. :)

Sufficiently low loss cable that you can afford to go 10 feet at 2.45 GHz has a diameter of 0.485 inch for the outer jacket. And it is a pig to terminate. For 902MHz to 928 MHz i can get you down to 0.260 OD. Cable attenuation above 200 MHz can eat you alive if you cannot afford the space for a cable with low enough losses.

Ten feet doesn't give much room for realistic cable routing.

I have a 10 dBi wi-fi antenna with a permanently attached 6 foot cable; net gain, a little over 4 dB plus a different pattern (no longer omni).

I assume you mean 4 dBi (gain over isotropic), which isn't much, can still have a pretty much omnidirectional pattern in two dimensions by flattening the pattern in the third. A dipole has a 2.2 dBi gain.

Yep. You can get useful length with problematic cables (large diameter, doesn't work so well with SMA sized connectors and TNC size is better but

10 concrete floors with 200mm (or 8") mesh is going to be a problem, and this stuff is even worse:

I assume some sort of retrofitted seismic strengthening.

Have you considered a treadmill?

Reversed threads are called left-hand threads

So the connector so socnstructed would probably be called

reverse polarity left hand threaded Neill-Concelman

Or RP-LH-TNC (maybe LH-RP-TNC)

- my stride is too long for most "home" treadmills

- my walking pace is too fast to "recover" from distractions like changing track on ipod, etc.

- while some can be programmed to simulate a walking profile (e.g., uphill vs. flatland), that's just one more thing to have to "do" (vs. walking out the front door and heading up the hill!)

- you don't get to engage your neighbors (fine, if you are a recluse...)

- it takes up a LOT of floor space (unless you buy a toy)

- it wastes a lot of money

- its boring (unless you're the type who wants to watch TV while "exercising")

I looked at a surplus treadmill from a cardiac rehab center. Well built (no doubt for high duty cycles and "overweight" cardiac patients). Lots of bells and whistles. Priced right.

But, took up one helluvalot of floor space -- I think it was over 9 ft long and almost 4 ft wide! If I wanted to waste that much floor space, I'd rather unpack one (or two??) of the pinball machines!

No, walking the neighborhood, to the library, etc. seems a far better solution.
