6 Meter Attic Dipole

Most of the antenna is over my swimming pool so that might be affecting the resonance point.

6 meter attic dipole.

Click here for detail explanation of how the ocf dipole works. Remember the ocf dipole has an impedance of 200 to 300 ohms so you will need a 4 1 or 6 1 balun if you do not use a remote auto tuner. I built the dipole and did some testing using my k3 s built in swr meter. Did some slight adjustments to the length and we re now all set to compare the vertical dipole i m currently using and the horizontal dipole in the attic.

This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up. The slick six 6 meter dipole can be supported from good solid pvc pipe at the center using u bolts fastened over the pipe thru the center insulator or you could use metal pipe and adjust the length. The better your antenna the more success you will have making contacts. That would have proven very helpful in tuning the.

I do miss having an antenna analyser that works at vhf. The infamous attic dipole. In the june 2008 issue of cq magazine i wrote about the difficulties of getting on 6 meters while living with covenant restrictions cc r prohibiting antennas. Feed it with 50 ohm coaxial cable as usual.

I measured it using a rigexpert aa 30. It actually seems to work better at 40 meters than my previous 40 meter monoband dipole. The 6 meter dipole can be designed for any portion of the 6 meter band you desire using the formula. The ocf antenna gives lower swr with wider bandwidth over more bands than the small length center fed dipole.

Inside the box is a 50 ohm 1 1 balun. The 10 meter and 6 meter ham bands. 10n6rdb antenna in the pictures the bottom horizontal aluminum tubing is a half wave dipole tuned to 10 meters that is all set to be fed with your 50 ohm coax. See swr plot for center vs.

1 i concocted a way to overcome these restrictions and with considerable effort was able to erect an antenna in the tight confines of my attic 35 feet above the ground. A ham radio six meter folded dipole antenna made of ladder line fed with ladder line and matched with a step down 4 1 coaxial balun at the bottom of the tra. I actually get 1 01 at 6 8 mhz and 2 0 at 7 3 mhz.
