Inverted L 160M @ F8DZY

Hi all, if you follow me on Twitter, you know that since some days, I am erecting an Inverted L for the Top Band...
After a lot of reading on the web and considering the "free" space on my property, I could try a half sloper and the inv L; my choice went on the inverted L.
This antenna cost me 0€.
Material ("in stock" in the garage) :
- (+/-) 42M of electrical wire 2.5mm2 (inverted L)
- 1 PVC pipe (cutted in 2 parts for insulators)
- 1 piece of PVC plate (base)
- another 50cm of 2.5mm2 electrical wire & a plastic bottle (beta-match or "hairspin")
- 1.5mm2 lenghts of wire I had from my previous vertical antenna radials' installation (8 x 48M)
The configuration of the property makes that the horizontal part of the wire seems like a sloper, but it's not... and it works !

 - Insulator (PVC pipe) : the end of the horizontal part of the wire comes here, slice it less or more in order to adjust resonating frequency... On the other side of the PVC is attached a rope, itself attached to a tree, with a counterpoise in order to slice during big winds. (Height about 10,5 meters)

- Look at this impressive sealed box ! ^^
Connection between coaxial and the beta-match is not yet soldered, as I still don't know if this Inverted L will be a permanent or a "winter" antenna...

- Some view from the top of the pylon (to NA), giving you an idea of the slope...

- Some pics during the first attempt... (R was too low)

After several up and downs, I decided to add a beta-match (hairspin) at the base, after several tests, mine is 8 joined turns (the picture below shows one of the first beta match coil tested)

I put 8 x 48m radials as I could, and connected them to the beta-match coil.
I also connected to this part the existing 48 x 24M radials from the HF3B vertical.

First tests were correct, I've been called by ZB2X from Gibraltar on my first CQs, whole Europe is covered (see RBN) . Some minutes later I was heard @ W1NT. A little bit early for NA...

Then I could work J5T from Guinea Bissau at the end of their DX-Pedition for a new one on TB !

During CQ WW, I could add YL, EA9, ZA & EA8 as new ones in some minutes... 

Now we'll see during the next months how it will perform... 

In final, as wrote it DJ0IP, all installations are different and will give good or poor result at different places... You have to test at your turn and find the good match ! Hope you enjoyed the read !

Sourcing : DJ0IP, F6BKD, F6DDR, I1WQR, F5ZV, F5AD, DK5WL, etc...

3C1L & VK9MA's chase : epilog !

Hi, I'm in late with my blog articles ! Radio-activity was good, and no time to update ^^

So, 3C1L was over after a long stay, it was the opportunity for me to add slots and a new band with 17M RTTY, 20M SSB and 80M CW !
So happy with all these QSOs, mostly needed slots... Good job guys & thanks !

Then, VK9MA Mellish Reef, I could fianlly add the 20M RTTY for a new mode !
4 QSOs, including 2 bands & 3 modes for an ATNO, that's not so bad ! Thanks guys !!

VK9MA Mellish Reef IOTA OC-072 : the chase !

Hi, finally the so expected VK9MA expedition is on air !
Starting on a week-end, huge pile-ups were previewed, and they were...
I tried on Saturday 4th in vain, tried again on Sunday morning in long pass where they signal was stronger, no more luck...
Then, at their SS, turning the beam on short pass was necessary and VK9MA signal peaked to S6, but too many callers...
Busy at home, I wanted to see what the sigs looked at in the middle afternoon and surprise, they're still on 20M CW and pile-up seems more readable (but still 9 or 10kHz wide !).
Sorry children, Dad have to try ! ^^
10 minutes later, I was answered by VK9MA for an ALL TIME NEW ONE !!!
Thanks for my 321st DXCC and 561st worked IOTA !

On Monday 6th, they are booming on 17M CW !
5 minutes only to find the good split and "in the log" again for a new band...

To be continued...

3C1L Equatorial Guinea : the chase !

Hi, I'm having big fun chasing 3C1L from Equatorial Guinea ! 
Before and after 3C0L from Annobon Island, I could log several new slots & new bands for this rare-on-air DXCC...
It started on October 20th with a 1st QSO on 20M CW for a new band, then, after Annobon return (where 4 QSOs -all new- were logged here), serious things could begin !
On November 1st, a 15M CW QSO, they were 599+20dB !!
On November 4th, I could log them on 10M CW (new slot !) in the afternoon & on 40M CW in the evening just after they QSYed from 30M (new band !) !
On November 5th, I could work them on 15M RTTY on my 1st attempt (15M was definately the stronger band from here)...

...and finally, after several days trying, I could be heard on 30M CW (new band) !

They should go QRT on November 12th, good luck to all !
