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).

your right

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.

6' of cable isn't going to realistically route vary far from the transmitter. It's not going to reach the roof from a desktop, for instance.

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

0.405 {10.3} and 0.485 {12.3} inch {mm} cables still do not fit well).

10 wooden floors perhaps

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.
