Peter, I hope you didn't fall into the trap of just comparing the optimum take-off angles. It's quite possible for a dipole with a higher take-off angle to be better than a vertical with a low take-o
Peter, "In all cases the dipole radiated at a slightly higher angle than the vertical, which is why the vertical is a better choice, sometimes, than the dipole for low band DXing." Steve G3TXQ ______

The moral of the story is "use red boxes instead of black to house matching and reflection transformers for beverage antennas";-). While the odds of a plastic box being conductive are fairly small, o

Hello, I know this is an age old question. What is your best recommendation on getting some ropes in the tops of my 80 - 100 FT (25 - 33 M) pine trees ? I have heard a sling shot or bow and arrow can

I used a half wave vertical on 40m above 130 radials 15-30m long. This vertical was tested for half a year against a straight dipol at 30m. There was not any path where the vertical came near the per
Sure it does, at about -3,8dbi of gain. Above all other ground except above saltwater the dipol will outperform the vertical in its broadside direction 73 Peter Paul, I'm sorry I've failed to convinc
The gain will be the same, there is no reason for being different 73 Peter What is the gain of the cage dipole at its 2:1 VSWR points over a single wire or element dipole at the same frequency points
I did a different approach when I installed my 40m 4-Square. I first calculated the radiator length for 6090kHz (100kHz below my target frequency). Then I resonated the first radiator by fine tuning
Oh, I am terribly sorry, that should be read 6990kHz 73 Peter frequency). Why was your target freq = 6190? -Rex K1HI Rex Lint Merrimack, NH --Original Message-- From: towertalk-bounces@
The gain specs are wish figures. A logperiodic equals in gain a 2-element yagi but differ from the lowest to the highest frequency when there are many elements on a long boom. Being a bit better then
Hi Jim, You could probably use any rotator with DC motor. I use a Prosistel PST2051 with a 600 ft. cable run. The connection to the transformer in the control box just needs to get rerouted to a high
