Generally, there are no restrictions as to manufactured vs home brew towers. Many building codes, including the Florida Building Code require aherence to a national ANSI standard, TIA/EIA RS-222, cur
It will NEVER reduce your property value.... Look for an increase in your assessment that is about the $ value that you put in your permit application. Mickey N4MB -- Mickey Baker, N4MB Fort Lauderda
I did the opposite a while back, took down the 6BTV for a 43' Vertical. 1. Yes. With a good ground.lots of radials, don't be surprised if the antenna needs to be shorter than you can adjust it. You m
RX was immediately noticably better. Noise sources, too. Works generally fine 40-10 meters, but it's a bit short for 80m, it appears. I can tune it, but I'm not happy with the results. I have about 3
Larry, You can effectively seal a double hung window with foam between the pane that's lifted and the other pane, like is done with window air conditioner installations. You'll need to rig a latch on
Jim has explained the optimum solution - windows are made for ventilation and light, not for passing things through. My house is concrete block and stucco, with rebar and a poured concrete cap, which
Folks, there are ONLY THREE eham reviews for this antenna. If there were 10 bad reviews from 10 different hams, I'd suspect the worse, but 3? The AV640 is a similar antenna (doesn't cover 80m) and ha
Believe it or not, we have rocks in Florida, too. I use a 1/2" hammer drill, applied to the top of the rod with an old deep socket. Unless I hit a boulder, it works very quickly, there's lots of grou
Hi, Mike, Depending on where you are geologically, "undisturbed" soil may be difficult to achieve. I was lucky in that my house is on a US Corps of Engineers built muck island, retained on all sides
Right. He first commercial gadget was the E.F. Johnson "Matchbox" which was an appropriate name, IMO. 73, Mickey. N4MB -- Mickey Baker, N4MB Fort Lauderdale, FL *Tell me, and I will listen. Show me,
Mike, I've spent a lot of my career servicing government agencies and spent time as director of technology for a county government. Like any workplace, 20% of the employees do 80% of the work. I don'
As always, it depends. Some inspectors are more thorough than others, some municipalities have more or less stringent standards. These type anchors are commonly used as tie downs for manufactured bui
Hi, Stan, This is going to be variable based on where your live (wind code, engineering and permitting) and what the antenna wind load is. For example, here is a self standing 45' 45G kit: http://www
I spent several years in my youth installing pay telephones for Southern Bell in the Atlanta area. I installed many (perhaps more than 100) 8' ground rods with a 1/2" rotary hammer and a cup device m
Let's think about the MFJ-259B for a minute. I spent an hour troubleshooting one that belongs to a local ham. It took a half hour to find a schematic and open the case. I found pretty much everything
I have a properly installed RCB-70 base for a Tri-Ex LM-354HD or LM-470 tower. I am going to replace this tower with US Tower HBX-555. I have engineering documents for a design to remove the "ears" o
Funny you should ask... I flew mine over the top of an 80 foot palm with 12 pound monofilament this morning to use as a messenger for heavier line. It was risky, but worked perfectly. No release poin
You're asking for engineering analysis of a non-standard scenario. Any advice would be risky. 1.125" bolts in a 2.5" diameter hole leaves a lot of space for fill. It appears to me that you'd want to
Scaffolding and pre-carved sections. No deaths in the construction, which is a wonder in that age: http://www.retronaut.com/2012/04/construction-of-christ-the-redeemer-rio-1926-1931/ -- Mickey Baker,
Caution using acetic acid (vinegar smell) based sealants for this or any other metal projects. There are others that work well (discussed in an earlier thread.) I prefer a light removable coating com
