[Repeater-Builder] Re: OT: Tape

I want to thank you all for you input, insight, and stories. You have confirmed exactly what I was thinking. I too have often experienced vinyl electrical tape getting gooey and sticky in high temp environments (automobiles). This is why I use heat shrink on most things. Also, I didn't think i

A pair of DBS dishes with a bi-quad antenna mounted in place of the feedhorn, fed by WRT-54G routers with DD-WRT firmware to tweak the power and turn off one antenna port will be perfect for this application. You can either flip the dish so the feed is on top, or mount the pole so it's horizonta

Re: [Repeater-Builder] OT: Tape

Another trick I learned is to make 2 wraps with the adhesive in (on the work) then fold it over and make your wraps with the adhesive out as your first layer before putting the mastic/butyl tape down. This will keep the adhesive from getting all over the work, especially when wrapping coax conne

RE: [Repeater-Builder] OT: Tape

This is my preferred method as well for sealing connector splices. However, I do three layers each time (one layer up, down, up again of 88, then the same of splicing tape, then again of 88). Overlap each successive wrap about 50%. Always, always, always do the last wrap in each direction goi

Re: [Repeater-Builder] OT: Tape

If you can get a hold of the 'real' F-4 tape that the Air Force uses, it will not leave any type of mess behind and it is not affected by UV rays. I've seen stuff exposed to sunlight for years and it was fine. A sharp knife or razor blade applied longitudinally will split it open and allow yo

Re: [Repeater-Builder] OT: Tape

Actually, this is how I've been taught by several RF engineers to seal outdoor connections... a layer of Super 88, then linerless splicing tape (about 1/2~1 inch longer than the 88 layer), then a second layer of Super 88 (about 1~2 inches longer than the splicing tape layer). Seals up the connectio

Re: [Repeater-Builder] OT: Tape

3M Mastic tape? Just remember, it'll end up sticking to anything else you stick it to *eventually*, often in ways that are quite amazing and not reasonably removed. I suggest a layer of standard electrical tape between anything you care about and the mastic tape layer (and another layer of ele

Re: [Repeater-Builder] OT: Tape

Rubber tape is good for high-vibration environments, where the insulation could get rubbed off over time. The rubber would get worn down before the insulation. Apply cloth tape over it to keep rubber from dripping off in high heat. Cloth tape is good for higher temps (won't stretch like plastic)

[Repeater-Builder] RLC4, possible to make one port a priority over the others?

Howdy, Is it possible to configure a port to be a "priority port" over the other ports on the RLC4? So if for instance there is an active conversation occurring on port 1 but then someone keys up port 4, the audio from port 4 goes out the repeater while crow-barring the audio coming in on port 1.
