I believe the best way is to determine the resonant frequency of each element using AutoEZ and then adjust the tips of you actual taper schedule/element to match the original antennas. If I remember
Everett, Not sure I understand the question. Assuming you are going to have the same length of boom on either side of the tower, your choices will be to have the driven element at approximately 22 fe
Jim, They are sealed and assume made to last for a long time running at high speed in other applications. I dont know but would assume in this light duty application they would last a lifetime. You c
There wouldnt be any difference in using the guy wires cut to resonant lengths and using the tower to hold up wire antennas in between your Mastrant or Phillystan guys. In both cases you probably wil
Yes, I have been using this stuff for many years for mast and element plate clamps. https://www.amazon.com/dp/B07X7MJJXD?psc=1&ref=ppx_yo2ov_dt_b_product_details In fact I have element plates holding
Any possibility that a flexible coupling of sone sort would solve the problem? Stan, K5GO Sent from my iPhone _______________________________________________ _________________________________________
Or slow it down by two or three to one with rotator outside of tower and chain drive? Surely a prop pitch slowed down by a factor of 2 with Green Heron controller ramping up and down would solve all
350 feet is about 5 quarter wavelengths at 3.8 MHz. Quarter wavelength is about 65 feet or so. If that thing is really 350 feet long you should see resonance at about 700 kHz, in addition to every od
If it is 300 feet total horizontal with vertical part at midpoint, I think it is resonant about 3.55 and 350 total horizontal about 3.12 Mhz. If you match it wherever it is resonant it looks like the
I have made a few over the years. I never did anything more than three pieces of angle across one face of the tower - one for the rotator mounted on a plate bolted to the horizontal part of the angle
What Jeff said was exactly correct. Maybe a better analogy could be used especially since you could have a lemon in any brand of vehicle and prefer one brand over the other. The POINT Jeff was making
Ive put a few items through the dishwasher over the years and always happy with the results. 73 Stan, K5GO _______________________________________________ ____________________________________________
Whats that thingy called that sticks up above the 55G mast that has the rotating antenna attachment gizmo (previously thought to be properly called a boom to mast plate)? Is it a tower, since it is f
Seems to me if you really believe mounting antennas on opposite sides of the mast is going to make a difference in whether the mast bends you already have a problem regardless of how you mount the an
Free standing? If not, I would drive something into the ground with slightly less diameter than the inside diameter of the mast and telescope the mast over the driven stake. Then it wont move at the
In preparing to head to ZF9CW in about ten days, I wanted to take something that would allow me to do a better job on my radials under my shunt fed tower. With the thing so close to salt water the de
Jim, Thanks for pointing me to that review. I looked at that picture. These are 304 grade stainless. DX Engineering's plate is the same - 304 stainless steel which is not the best for corrosion resis
Is there anyone out there who repairs Yaesu rotators? Stan, K5GO _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@conte
Thought I would share this link. I bought some electrical tape recently and didn't really want to pay the exorbitant price they now have for Scotch 44. In my opinion this tape is every bit as good an
