KY6R Optimized 40M Loop Frame on the Yaesu G450A

Getting the antenna square took some time and engineering I got really close today to getting this on the air (but it took a bit longer than I expected). The frame is square and I have the wire threaded through the top support element. Tomorrow I will have the Wellbrook FLG100LN Preamp on the front and the 880 ohm resistor on the back. I…

Dual KY6R Optimized 40M Delta Flags – Progress

The first flag rotator with cable PVC pipe is almost ready (I need to trench it) I took down the W6LVP loop and moved the rotator to the first flag’s mounting pipe. I also got the second flag’s mounting pipe cemented into the ground using fence post concrete: The second aluminum pipe is now curing and will be ready late tomorrow I won’t receive…

KY6R 40M Optimized Delta Flags Separated at 80 Feet Apart

At 80′ – I can rotate the second KY6R 40M loop I have a choice – I can have the second loop at 100 feet (where it would have to be fixed) with a bit better performance than at 80′ (where I can rotate the second loop). I’ll choose to rotate the second loop because the performance is not that far down, and rotating…

The DXE NCC-2 at KY6R

I’m switching back to how I used to use the NCC-2 – this time on 40M instead of 160M I know that this mode of the NCC-2 works like a champ – but this time, instead of using two Wellbrook ALA1530LNP loops, I will use my KY6R 40M Optimized Delta Flags. I think I will opt for using the preamps and 75/50 ohm modules…

Two Phased KY6R 40M Optimized Loops = 11.6 RDF!

Two KY6R Optimized Loops separated 100′ – an RDF of 11.6 and more gain Looking at EZNec, there is a very compelling reason to go with two KY6R loops for 40M. In fact, I also modeled the W6LVP loop with one KY6R Loop – and it pales in comparison. So, the plan will be to put up a second KY6R Loop – but it…

KY6R Optimized 40M Loop – Next Step

The feed line will run along the bottom 1 x 2’s and to the 75 / 50 ohm transformer. I will use a plastic electrical box to protect the transformer and resistor from the rain – and use 4 bolts to hold the ladder line that comes down from the apex and then the bottom ladder line that runs along the bottom elements. The…

Building The KY6R 40M Optimized Loop

The double walled pipe will fit in the top part of the Yaesu G450 rotator. Bolt the pipe with the redwood inside and then use two U bolts to hold the antenna frame to the pipe.  When redwood gets wet it does get a little bit heavier, but is usually doesn’t warp or split like other woods do. I was going to use fiberglass…

KY6R Optimized 40M Flag Hits 55 dB F/B!

Getting the antenna up to 2′ and changing the load resistor to 880 ohms did the trick Updated antenna – I do think I’ve squeezed every drop of performance out now! I have found that the W6LVP loop on 40M is not very directional at all. I will move the Yaesu G450 rotator to this new loop and use a cheapie RCA TV rotator…

Surprise! The KY6R Optimized 40M Loop is GREAT on 160 – 20M

The KY6R Optimized 40M Receiving Loop When I developed this loop I was intent on squeezing out every bit of performance for 40M. I basically live on 40M any more. Just for kicks I then took my EZNec model and plugged in 30M and then 20M – WOW – both were very respectable performers. Tonight, just for laughs I tried 160 and 80M and…

KY6R Optimized 40M Bi-Directional Loop

Two loops on one support A few posts back I shared a model for an optimized 40M receiving loop. Last night I checked to see what it looked like on 30M and 20M – and was very, very pleasantly surprised. In the past, I had simply fed each corner of one loop with a feedline from the DX Engineering NCC-1 that I had –…
