Dual Band Yagi antenna 2m/70cm

This antenna already keep it in my store for long time,
It is time to "make up" Hi hi
Actually, nothing much , just add some more elements...
and eat few more pain killer for myself, haha...
Then , TA TA .. this antenna come alive ,
become a DUALBAND antenna ,
and tested 2m with my MFJ-259B
144-148 not more than 1.5 SWR,
because it is a 50Ohm feeding antenna with 1:1 balun.
but on the UHF site ,have to test with my FT897.

On UHF site, a bit narrow la ,
432-437Mhz below 1.5SWR
I think it is still ok la..hi hi...

The SO239 socket is at the back, it make more EZ
to plug in and out !!
(actually , nothing special la, haha...)

11 ele HF tri bander DC311E3


Very HAPPY with my D11E3 tribander yagi
so far with a more than 10 contact on 10m band
with JA, HS, BG7, 9W8, ZR1 & VK station.
Finally I bring it down and put this C3-E up .

This is a Tribander yagi with 7 elements,
it is lighter than D11E3, more EZ to set this thing up,
I already have some contact on 10m band with BG7 & VR2 station,
Both station get a 59 report .
Has try RX on 15m band , A lot Europe station with s3-s8 Signal.
and I`ll try to get some 20m station later ...

20meter and 10meter Mobile Antenna (Helix)

This antenna can be FIT anyway with a good GROUNDING
Resonance (x=0) for 10 and 20 meter band.
I rx some station when I test the 20 meter band,
station from VU, VR,VK, BG and BA
all station RX 55 !!!

Tested on my FT897 with a GOOD GROUND connected.
1:1 swr on 14.200 !!!
also tested with my MFJ-259B antenna analyzer.
Match efficiency more than 95%
The only problem to use this antenna,
" Must have a GOOD GROUNDING !!"
