Hello Booty Monster: You don't want that type of Balun feding a "Unbalanced Antenna" The Colied up coax is trying to feed the antenna with equal currents, not how its designed. Try a 9 foot length of 7/8" OD Aluminum Tubing fitted over the PL-259 connector on the antenna, and allow it to...

Hello Doc: What free time?!?!..... Hello Booty Monster: Yes thats what I sent and the claims stand. Jay in the Mojave

1/4 wave ground plane antenna Hello All: Ok got a few e-mails on this subject. I have built a few of the 1/4 Wavelength Ground Plane Antennas. I was aked by the local hams for a 10 meter 1/4 wave antenna for a beacon transmitter. Because the 10 meter band is dead like the 11 meter band, the...

Hello Tallship: Yeah what those other guys said! Have you ever nailed your Calculator to the wall in the Garage because there's just too many numbers or your just slow. I have! Heres a good rule of Thumb way of doing that in your head. If your mast heigth is say 30 feet high, then the...

Hello Cajun Invader: Give Steve a call (661 256 6976) he has answered many questions on antennas and there installation. Ask him to give you my phone number and I'll talk to you also. Any one whos says their an expert on antennas is lying to you! We go ahead with antennas after a long...

Hello Mole: Wow a great article on the Yaesu VX-8R, and you have the unbalanced state of mind to actually put it under water. You make me feel normal! Ok I am sure HH will come up with the HT Radio that I feed to Mr. Band Saw. I'll post here so he won't beat me to it. But the HT had it...

Hello All: One thing that has to be considered about Coax is that its apart of your antenna system. That is its just as important to use good Coax as it is to install the antenna right the first time around, I know the feeling to come outside and see the new Wa-Zoo Antenna lying down in the...

Hello Lazybones: Yes this can be done using ladder line. But you will need Impedance and Balance matching device at each end of the Ladder Transmission Line. So now you will need the Ladder Line, and two 50 to 450 OHM transformers or matching devices. And the Ladder Line will need to exit the...

Hello Splash1: Good points made here by the others. I have seen some fiberglass none ground plane antennas have ice or water in the base of the antenna where the matching circuit is, throwing off the match some. And of course rusty connections by none stainless steel hardware can cause bad...

Hello Psysco: Looks like it needs more ground plane. Temporarily add some 9 Ft long wires from the base ground and lay the wires and see if that lowers the SWR. If so ya need more ground plane area. Jay in the Mojave

Hello JPT: I have sent you a private message, with my phone number. Jay in the Mojave

Hello JPT: Kind of hard to see all the tower with just a couple of photos. But to me it looks like a light weight to maybe medium duty tower. NOT made to install a large Yagi Beam Antenna on. Possibility made for small communications and TV Antennas. Case in point: A gentlemen near Mojave...

Hello Mole: Yeah does it have a peak or null any were? Or is just get a higher XL as the frequency gets higher? Now that you probably put the coil back.... Jay in the Mojave

Hello Mole: Connect one side of the coil to the center of the SO-239 and the other end of the coil to the SO-239 shield or ground side. Jay

Hello Mole: Disconnect the coils from the dipole wire, and connect the coil to the SO239 connector. In the Xl mode the coil should be measured around the 40 meter band, and a high XL measurement, I would think. And what frequency has the highest Xl. Jay in the Mojave

Hello QRN: That might be a good call as the inductance from Moles dimensions figure to 173 uH of inductance. And I figure around 3 pF of Capacatance to get close to 7 MHz, as a resonate LC type circuit. I guess we need to measure the coils on the antenna analyzer. I wish I had more time...

Hello Mole: Ok we are back at square one, it appears that the coils in theses Alpha Delta Antennas are loading coils and not Traps (Traps = using a coil and a capacitor to make a band trap LC type circuit) Again back to the discussion of the broad band 40 meter antenna having a wider...

Hello Moleculo: Look at your Alpha Delta Dipole Antenna Coils; is there a Capacitor inside the coil assembly? Making it a tuned trap? Or is it just a Coil. Again the Antenna Analyzer connected to the coil would tell you this by being resonate somewhere in the 40 meter band. But you would have...

Hello Doc: Good to hear your doing well. And you enjoy the work. The Alpha Delta Antenna that I have has no capacitor in the coils, so I am thinking the manufacture made the coils to have enough inductive reactance to act as a choke to the 40 meter RF Energy, and a loading coil to the 80...

Hello Doc: How have you ben doing? Doc said: I'm afraid not. That coil is a loading coil for 80 meters, has nothing to do with the 40 meter antenna which is located below the 80 meter antenna. The 80 and 40 meter antenna is one wire, with the loading coils are for 80 meters. Thats why I...
