Hi I'm back on this list, just for a while to participate in this discussion. (I usually troll the archives). 1. The electrolysis is made worse by the use of a copper ground rod. This explains why th
In this height range (~70 feet), given take off angles and vertical propagation angle info from N6BV, I calculated that every 10 feet was 1 db, on 14 MHz meters or higher. That's why for my setup, I
I vote for the STeppir 3 element. Much less mehcanical complexity, perfect gain and f/b on any freq you want. Never owned one, but would buy one in a heartbeat if my KT-36XA fell down. Never owned a
I had questions about breakage on the Tennadyne logs. First time around, ice buildup caused one of the longest elements to literally tear a big hunk out of the boom. We took the back part of the ante
Your indicator problem *could* be many things. Obviously wiring, problems in the control box, mechanical disconnect between pot and upper housing, etc come to mind. it *could* also be the problem I e
I've done the same thing, supporting a pair of 80m loops, with a 20' long crossarm made from 2" PVC pipe. The crossarm is supported from above with a truss. Before you jump on me about how lousy PVC
Guy I don't think you can just use the new dimensions. There are other changes (mechanical) which can affect trap resonant frequencies. A call to Mike at M2 will give you all the info you need. I hav
Let's not forget the KT-34 and KT36XA, now resurrected by M2. ..or perhaps we should leave this choice as a well-kept secret! I've had a KT36XA up for a year now; the mechanical issues are completely
Well, there seems to be two approaches t lightning: 1. Protect your equipment in the event of a hit. 2. Do something that reduces the probability of a hit. My question is : Can approach #2 reduce tha
First, I wouldn't worry about a swinging gate hitting a tower leg. It'll just stall the rotator, which is no worse than having a stuck break wedge. 73, Tony K1KP
Well, lets see: 2.16 dB loss => 60.8% power delivered to load 1.40 dB loss => 72.4% power delivered to load assuming 1500 watts in, the difference is 174 watts. Look at it this way, if you use the lo
Somebody on the list must actually own one of these!! So far no reports! I'm 99% ready to buy one, but it sure would be nice to hear someone's first hand experience Quality? Construction? Instruction
Hints & Kinks for KT34 rebuild -Use a plumbers pipe brush for cleaning the tubes. This is a handy tool with wire brushes for cleaning the inside and outside diameters of tubing. It will clean the alu
Back when I actually had time to contest, I used 1/16th amp fuses for receiver protection. That's .063 amps. I put them in series with the antenna lead, between a receive bandpass filter and the rece
It was me... The following measurements of resonant frequencies were made 8/20/96 on my KT-34XA. Each element was removed from the boom, separated a reasonable distance from the rest of the antenna a
It looks like there's quite a bit of interest in this - why doesn't someone put together a kit of parts for the upgrade? You can put me down for one! -Tony, K1KP _____________________________________
I have a KT-36XA 9 feet above a 40-2CD. I have noticed a serious interaction between the two - specifically, the SWR on 40 goes above 3:1 when the XA boom is parallel to the elements of the 40 - i.e.
I used one of these to make connections to the driven element on a 40-2CD. 1500 watts, no problems yet. Unless the SWR is high, or there was a defect in it, I can't see how this simple connection cou
What's the best way to clean old, brown oxidized stranded copper wire so it can be soldered? Many times I need to modify or repair old wire antennas. I've tried sanding with 400 grit and also wire br
