Fiberglass pole
Hi,
althought I wrote about the telescoping fiberglass poles in preview articles (6 parts) it seems to be never ending story...
As I promised last time I am continue looking for another suppliers to get another source for Fiberglass masts or poles to use it as support of receiving Delta or inverted L or another types of 160m antennas for DXing.
If You will visit the web of JH1GVY then You will find there very nice table of suppliers for poles usable for our ham radio hobby and 160m antennas.

Feature

All parameters are visible in the preview table so comment is not needed.
What is very interesting from my point of view are the "errected/collapsed" diammeters of the poles. 48/11mm for 10m pole and 86,4/12,4mm for 18m pole. It sounds to me much better then the "strongest pole in the history" comes from Spiderbeam here http://www.spiderbeam.net/sb/index.php?cat=c2_Fiberglass%20Poles.html&XTCsid=1c75f2c0d6f29714b2c237b66eb4207f
about which I talked in an article Telescoping Fiberglass Mast - part I. There You can find that the pole from Spidebeam 18m tall has 73/4mm of diammeter only.
OK, the question is what it will do in the wind and which differencies are in the materials in these two cases as Spiderbeam talking about "specially reinforced multilayer winding"
Well according to the technical parameters of the W-GR-1000H/1800H it comes to be one of the favourable pole for my antennas suports on 160m.
Any comments or experiences with that pole?

Hi Petr,

Great website with very useful information.

Have you had any luck in obtaining a W-GR-1800H

telescopic pole ?

I have tried e-mailing the address you gave and contacted several companies in Japan but no one either replies or is able to ship to Europe.

Looks like it's a nice item, but very difficult to obtain outside of Japan.

Regards,

Martin - G8JNJ

Hi Martin,

thanks to visit my blog. Yes, I have the same problem with purchasing the poles from Japan. I tried to email to few of re-seller in JA but no success. Also I tried to contact directly manufacturer but no reply. That is the reason also why I posted overe here informations about that poles as I am believing that somebody will let us know how to reach them...
