Bill, if you want to get on 12 and 17M on a regular basis, the XR5 will work much better than the C3. Even though the C3 works on 12 and 17m, it has a fairly high swr on those 2 bands. Most likely yo
I have been using nylon insert ss lock nuts on ss bolts and u-bolts. I have not had any seize or loosen. Also don't need a lock washer. The only pain is that you can't hand tighten them. You need to
Why not leave the power constant and use a switchable attenuator to keep the s-meter constant? That would seem to give more accurate and more repeatable readings. N2TK, Tony Frankly, I think these ar
Years ago some folks bought front end pass band filters for 40M. If I remember correctly they were for notching out the foreign broadcasts on 40M phone. I believe they each covered about 20KHZ of the
I have been using a bic candle lighter. They are about 8" long and only cost a couple of bucks at Walmart. It has a small flame which doesn't blow the igniter material. I wear leather welding gloves,
Yes, you can put it that close to the C31 without a problem. I could not tell a difference in bandwidth, swr and comparative signals when I had it spaced between 7 and 14' apart. Seems the MAG240N do
Pete, The MAG240N and EF240S seem to be two different type antennas. The "N" series has the linear loading moved out away from the boom. N2TK, Tony --Original Message-- From: towertalk-bounces@contes
I used 502 insulators. I had them and it seemed an easy way to make the transition using guy grips. N2TK, Tony I'm wondering how most folks make the transition from Phillystran guys to EHS steel for
Well at least I get to live that dream twice a year in the Caribbean. But to be competitive there you need to apply the same rules as up in the frozen north of New York. N2TK, Tony Ya Know there is a
Hi Tom, When I had a quad and monobanders, the quad was always quieter from snow static than the monobanders. Was wondering if the SteppIR would be quieter than a regualr aluminum beam during a snow
Don't let Jay fool you. Sharon does all the work. Jay just spends time in the sun sucking down Wadadli's. At least that is what he and I used to do on Antigua. N2TK, Tony FOLLOW UP: Thanks to those w
Looking for suggestions with a Cushcraft A3 problem. Up till this year it worked well. The swr was minimum at 14.1, 21.2, 28.4. Now it resonates at 14.5, 21.2, 28.0. Compared to a C3E on another towe
Tnx for input. New Buryflex to the antennas. No water in the traps. Been running 1.5KW through the contest weekend with no change. N2TK/NP2, Tony _____ Three things you might want to check: Crappy co
Hi Bill, In the corrosive soil here in New York, #4 stranded copper wire lasted about 6-7 years before I could pull it off the cadweld. Exposed aluminum sheathed hardline lasts even less. Switched to
Hi Tonno, I use a 3' X 3' piece of aluminum mounted on the wall in my basement. I have all coax and control cables go through ICE lightning protection devices. I mounted a coax switch, HF, 2M and a 6
Peltier devices (thermoelectrics) are commonly used in non-compressor heat exchangers for several years. They eliminate the vibration and possible contamination caused by compressor heat exchangers.
Hi Joe, Would be curious as to the heights of the antennas and are they all on one tower? What I have found in a few different configurations of monobanders and tribanders was that the lower antenna
Hi Jim, I have MAG240N (90') mounted above a C31XR (82') so some of the same things will apply to your setup. The MAG240N is a very nice antenna. It covers the entire band with decent F/B (the 402-CD
I use 10' of EHS for the lower part - one end on the turnbuckle with a thimble and a guy grip and on the other end I use a 502 insulator (cause I had them) with a guy grip on one side for the EHS and
We have an opportunity at WP2Z to put up another tower. The owner of the house would like it to be free standing. We would like to put up a 70' tower so we could raise the height of the 40M beam (Cus
