I was lucky enough to get several sections of Rohn 25, and included was a homemade Hazer. I have never seen Hazer up close, but from the pictures of the Glen Martin Hazers, that look like they are bo
Is there a source of 3 inch material i can use for my old Kirk Delta Loop that is reasonable? I think I can use 2 6 foot sections, since the boom/mast clamp looks like it would easily splice 2 sectio
I am planning on putting up 60 ft of 25. I would like to tilt the base over on rare occasions. Is it best to just buy a hing plate designed for this, or maybe the 3 ft sections that can tilt? I usual
I have been thinking about putting up a Rohn25 with a homemade steel welded Hazer. From what I have read, if you do not want to do any climbing with the Hazer above you, the tower will be temporarily
When I lived in FL I had a Hygain 204BA at the same height as a TH3 (the 3 el beam) and I could barely ever tell any difference on RX. The TH3 has less bandwidth than the TH6 or TH7, but is only a li
I have found aluminum tubing at the local metal salvage yard. Normally you will find tons of steel, but here, they keep a section of aluminum sheet, tubing, pipe, etc. More likely you will find very
I am curious about this: I am experimenting with a 2 element beam for 20 meters. It is driven element - director arrangement. I haveit near the ground with the director near the ground and the driven
I am wondering if my problem with the yagi is that I am using an old driven element clamp that came from an old hy gain beam. Could the capacitance from the driven element clamp (grounded) to the dri
I ended up changing the director to a reflector and the antenna resonatews fine now. I am not sure why a de-dir would not work. Doug N4IJ _______________________________________________ _____________
I am getting ready to raise an antenna on a rohn 25 and homebrew steel hazer installation and was wondering the best way to hange the coax, since it can't be secured to the tower. My thought was to j
A recent post made me think of this question. I have been playing with the free MMANA modeling software, as well as the older Yagimax. My first models were the usual dipole etc. I started playing wit
I can only think that I have not modeled the taper correctly in mmana... Doug N4IJ _______________________________________________ _______________________________________________ TowerTalk mailing li
Seen a few posts about putting the moor capacitor next to the rotor, rather than in the control unit in order to enable better turning (less slugishness). I have a problem in getting the antenna to t
The rotor is on a tower and the run is about 275 ft from the shack. What is the best way to get more response from it? At times I have to rock the antenaa back and forth to get it to even move. I am
The rotor has always been sluggish but has gotten worse, maybe due to colder weather. I guess I will do as one of you said and put a small series xfmr to boost the voltage. That would be easier than
I am in the thinking process of building a 2 element 15 meter delta loop beam. I found some Kirk mounts for a 3 inch boom. All of the literature I have read suggests reflector = 1030/f and driven = 1
I have my 60ft aluminum tower titled over, primarily to refurbish the Ham II rotor on it. That completed, I started examining all else on the tower. I have a 1/4 wave sloper (coax shield grounded to
I had read that after MFJ bought HyGain that quality had suffered. Is that the experience of any recent purchasers? I bought one from DXengineering the beginning of March. Hy Gain LJ-203 Both inner t
When I bought the HyGain LJ203, I was buying HyGain antenna (I thought), and they have always been known for mechanically well built antennas. The only reason I bought rather than built is because af
Getting ready to take down my beam and rotor. The brake does not work. I hear it click when it is energized on the tower. Would that mean a spring might be broken ? Rotates fine - wind blows it whate
