Actually, Chris, the SNV12 works fine without a ST.? I have on on my repeater for a while now.? Just too bad it's so expensive.

Correction, APS750 (Tripp lite).?
I've had good luck with APC inverters. I have a WISP site that experienced a failure of a VERY (+$2k) expensive ICT switching power supply/batter charger. Replaced with a $279 APC750 which efficiently runs the entire cabinet and a new pair of Interstate AGM 100a batteries (under $200 each vs. $700 each for orange). Has been running flawlessly for 3 years now without failure. Batteries still load test within spec (although I've recommended replacing them due to age and exposure to extreme temperatures). I actually expected the APC750 to have cooked them by now, but to my surprise, it hasn't been an issue.?

TrippLite products aren't any better as far as SLA "battery management" - just float-n-hope for that recurring revenue stream of replacement batteries or entire units.? ?
We know and can do better.
An aside - I was fortunate enough to be able to snag 36 100+ AH 'sealed' AGMs from a to-be-upgraded data center UPS (wish I could have gotten all 120 of them... but truck and backyard can only handle so much) - only 3-4 years of standby service, very few "wait for generator" cutovers.? The UPS BMS must have done a good job as all of them have been consistently 12.4-12.7 v open circuit sitting idle, all take a charge well, and the 'maintenance' shot to 14.4 or so.
Two of them now support 90% of my shack, charged/maintained by a Progressive RV 'smart' "charge controller".? I may add another two to the stack so I can run the ALS-500M off them as well.??
Eventually 2-4 of them will end up buffering gen-start delays for three repeaters at a commercial site - just need to get another smart charger.

The Real RFI-EMI-GUY
|
Dan,
This is the way we did it for LDF4-50 Heliax, because I did not wish to place holes in the siding. The poured concrete foundation is 10 inches thick, so a 3/4" hammer drill was rented. There is just enough room for several parallel runs of tinned copper braid to go between the Heliax polyethylene jacket and the ID of the concrete hole through the concrete foundation. These straps go from the Polyphaser just inside the basement wall (that is grounded to the duplexer, radio cabinet, etc with much wider straps inside the basement). I probably should have rented a 1" drill to allow for thicker straps. The Heliax travels? inside buried conduit and the Heliax corregated copper shield? grounded at the antenna end and to an outside perimeter ground at the house end. At the house end, the straps from the repeater are bonded just outside the foundation to #4 solid copper wire that connects to the perimeter ground consisting of 8 ft ground rods and more #4 copper wire.. Grey silicon caulk seals the perimeter of the opening inside and outside the house. If the house is sold, just fill in the hole with hydrological cement. Possibly someone will say we risk an exploded foundation with a direct hit, but there is a ton of underground bonding out of sight, so my thoughts are the strike will be much attenuated before getting to the foundation????

This is Repeater-builder and there was no mention of a home - therefore it was assumed - and still is - that this solution is intended for a repeater site.??
I also disagree that this solution is inappropriate for a home.? A single or double port plate is much better looking than the hacked solutions many come up with.? ?Whatever you do, DO NOT use foam (great stuff, etc) to seal an entry.?

Remember you should have a ground kit on each cable outside of this port bonded to your EGB and a PolyPhaser on the inside bonded to your MBB/MGB - so installing this should be as easy as pushing 1 ft of cable through the port, installing the cushion and boot, tightening it up, and connecting the coax to the PolyPhaser.? Make sure you leave the provided rubber port covers on any unused entry ports.? Whatever you do, DO NOT do the hack thing and try to turn a port cover into a boot/cushion.? I have seen this too many times when idiots take a utility knife and just cut a hole - then they may try to seal it with Butyl which dries out and falls off over time.?

Re: WSJ: Hytera and other brands banned by FCC
If you read it you may not have fully understood it.
It's an R&O with a further NPRM to follow
For those of you running commercial repeaters, MAYBE there's an
issue (will all depend on whether the FCC can really set rules to
enforce the protocols listed).? For those of us in the Ham
community, this has no effect.

The quick takeaway was Hytera is on the bad list and that can directly impact our efforts with repeaters. So I showed it in context and if the reader wants to follow up with the WSJ, have at it.?
