I have documentation on both the standard LM-470 remote and an after market remote control. I can email them to you as attachments if you want. de Paul, W8AEF ________________________________________
Every vhf M2 antenna I have modelled have excellent patterns. Don't have anything more than 5 elements by them but I highly recommend Mike's designs. de Paul, W8AEF __________________________________
You may want to consider parasitic feed. That could simplify phasing a bunch. And you may find that vertical dipoles are quicker to deploy (depending on the frequency) de Paul, W8AEF ________________
I have experience with 4 square phased arrays. Over a dozen so far. The advantage of parasitic feeding is simplicity. I erect the 4 elements with elevated radials in their calculated positions (.22 w

I agree with: Bob - I'm not a balun expert, but would recommend you try the Palomar BA-8. I've been using them here. They seem to work and there are no delicate windings that might arc over under hig
Is the BA-8 that much different than the BA-58's? The '58 does decouple the feed line from the vertical dipole arrays by my field observation, and that is why I use them. The routing on the feed line
Just for yucks, bring up W6ELprop and: insert 23 degrees as your Minimum Radiation Angle (Options - Prediction Parameters). Then run a prediction to a country maybe 10000 Km away. Look at the predict
My point is that according to EZNEC 3.0, a dipole at 1/2 wavelength above ground over salt water will have its major lobe at 30 degrees above the horizon and have a gain of 8.36 dBi. 15 degrees it ha
That should be "Obviously that IS true". In practice you will find in the vicinity of 8 dB loss per F layer hop. And what you have not done is play with W6EL Prop and see what the differences in F la
Thin wall PVC is good for about a year in the Arizona sun. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA XZ0A VU7RG TX5C _______________________________________________ ______________________________
Antenna gain is one thing, path loss is another. As I recall Steve's question was 'why does EZNEC predict higher gain for a dipole than a vertical, but in practice I see the vertical outperforming my
Too many antennas is like too much money - no such thing. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA XZ0A VU7RG TX5C _______________________________________________ _______________________________
Be careful with cable company hardline. It is probably 75 ohms impedance and when you connect it to 50 ohm coax (RG-214) it will become a 1/4 wavelength impedance transformer and mess your antenna sy
Yup. But figuring out the 1/4 wave, or odd multiple, frequency, is the trick. Oh, by the way, we have a short piece of 50 ohm coax on both ends of the 75 ohm hard line, plus a balun at the antenna en
Very important when using elevated radials: they will affect the resonant frequency of the element. When I installed my 4 squares I first installed two wires in the form of a 1/2 wave dipole (fed at

This is a U.S. Tower MA-770MDP 75' crank up tubular tower, with MAF 770 raising fixture and MARB-770 Rotor base. Includes limit switches. Power up and positive pull-down. Sorry, no controls but I do
The idea of a patch panel sounds good to me. I thought I was being real smart when I positioned my operating desk 18" from the wall so I could have access to the cables. Should have been 24" <grin>.
How many hams does it take to identify a shack ground? Too many. Time for me to take another extended vacation from this reflector. de Paul, W8AEF -- _______________________________________________ _
