Hello to all.

First sorry for my bad English language, you may find english mistakes in my post.

I am FO8RZ Phil in Tahiti until 2011.

I am running 100 watts only in CW and sometimes RTTY.

I use yagi up 6 meters for 10-15-20, a inverse vee for 40-80, and HF6V (with warc kit) for 30-17-12.

I took also from France the 160 meters kit.
I used it in F, but it was very hard for me to contact stations out of Europe.

Many stations asked me to operate on top band. So, I will install this week-end the 160 meters kit on the HF6V.

I would like to know the length of the radials I have to use.

My garden is not big, the antenna is close the neighbour, so impossible to put 150 radials on 360°.
I fou want to see how is installed the antenna, go to

On the butternut notice, they tell : L = 240/f
L in feet
f in Mhz

For 1.820 Khz, it is 131.87 ft 

I think, I will be able to put only 2 radials.
The first beamed to the 045 (USA) on 21 meters and after with a 90 corner to the right.
The second one beamed to the 180 and with 1 corner and beamed after to the 045.
My garden is not a big one.

Is it better to use 1 radial beamed to 045 or 2 ?

All the best 73

FO8RZ Phil
