thanks Jim, I am going to measure the current in each of my 4 elevated radials and see where I stand. Bob K6UJ 73, Jim K9YC On Sat,2/27/2016 11:43 AM, Robert Harmon wrote: I use four elevated radials
Jim, That GE stuff sounds great. I would also like to find out if is still available. I am putting up a new yagi soon and would like to try it. 73, Bob K6UJ I'm not advocating anodizing antenna eleme
I like the idea of spraying on a protective coating. Glyptal clear insulating varnish spray was suggested earlier and was reported to last quite a few years when sprayed on aluminum antennas. I have
Gary, Thanks for sharing the info on coatings ! I have been trying to find something suitable. Bob K6UJ On 3/21/16 10:22 AM, Gary Johnson wrote: An effective clear anti-corrosion coating for aluminum
I'll chime in. Like John, I would give priority to having a quality Amphenol SO-239. Bob K6UJ On 3/24/16 7:21 PM, john@kk9a.com wrote: Many companies install them on the outside of the enclosure if t
I am considering getting either the Array Solutions RatPak or a DX Engineering remote antenna switch. Any feedback on either of these, positive or negative ? thanks, Bob K6UJ ________________________
Jim, Thanks for the info. I will check out the 4O3A. I have never used a remote switch before and wanted to get the most reliable unit I could find. 73, Bob K6UJ On 4/12/16 9:26 AM, Jim Brown wrote:
thanks Joe, Bob K6UJ Stick with the switch that uses enclosed relays with higher impedance coils. The "open frame" relays (even with a carbonate cover) with low impedance coils (higher current) are m
I have always noticed a slight change in the swr with hf yagis when it is raining. Just a minimal change though. Nothing like what Gary, K9RX reported. Bob K6UJ 73 ES DX, Gary - AB9M Ive had beams si
Jim, Would it be possible to replace the relays in the RCS-4 with vacuum relays ? Probably not enough room ? Bob K6UJ I have three RCS-4. Thru the coax switching, never a failure in 4 yrs with legal
Jim, Very well built. I am curious about one thing. Their write up states that this unit uses 4 cascaded ferrite cores. In the picture I can only see 2. Thanks for sharing ! Bob K6UJ On 4/19/16 3:30
Chuck, I emailed MyAntennas this morning and they got right back to me. You are right, there are two stacks of two. Bob K6UJ Chuck W5PR Jim, Very well built. I am curious about one thing. Their write
Jim, I am using your choke design on both of my beams. With all this discussion on chokes it got me to thinking. My tower is only 10 feet away from the back of the house. I'm not sure how much noise
I have a 300 foot spool of Times Microwave LMR-600, still in its ship wrapping. Also have 10, Times Microwave EZ 600 NMH D fittings, still in unopened packages. Will sell for all $425.00 plus $40.00
The LMR-600 cable and fittings I posted earlier for sale has now been sold. 73, Bob K6UJ _______________________________________________ _______________________________________________ TowerTalk mail
I am still learning how to deal with common mode interference, and I am still very much a work in progress :-) Below are two sites with info on this subject that some of you may not be aware of. Firs
Why is it that I can get both male and female N connectors to go on the end of coax but only male UHF connectors (PL-259) for mounting on coax ? Bob K6UJ _____________________________________________
Thanks to everyone for informing me of suppliers of these fittings, much appreciated ! I didn't think they were available and the only option was to use barrel connectors. I need to wake up and smell
I agree with Tod. 73, Bob K6UJ There is indeed an RFI reflector. But, few if any, TowerTalk guys are on it. Admittedly this thread does not help guys assemble, purchase,design or install towers. It d
Grant, Thanks for the video on Nord-Lock. I am impressed with the product. I was surprised that the lock nut option didn't secure better in the tests. I always thought this was the most secure method
