But you could try tuning it to see what results you get or extend the spreaders and add you own 40m element. you could ask the design for advice also - G3TPW Steve Webb. Do a search and visit the "WEBB" site .... Hi Hi 73 Martin |

Are you talking about the antenna from the UK? If so Its 20 to 10 only.

In the absence of anything else, you can always give it a try on air. Antenna's are very funny things -- you would sometimes be surprised, especially during good signal conditions at which times I have successfully loaded up my toolbox while it was lying on the floor and worked a few stations! For my first 25 years of hamming I was always in locations where I could not put up a decent antenna. Using random wires and assorted other antennas, very few of which could rightly be called 'decent' antennas, I managed to get out and have a good time on the bands using an ATU and loading anything at hand! On the other hand, you could always make the cross arms longer and fit a 40 meter element on it. Another alternative would be to use a loaded element.

I should have said Load -- I guess it depends on what you call tuning. What the ATU does is 'match' the transmitter to the load. It does not 'tune' the load. The term 'tuning' and 'loading' are frequently used interchangeably in the case of an ATU. This is not intended to start an infinite thread of debating! :-) Irv VE6BP -- -------------------------------------- Diagnosed Type II Diabetes March 5 2001 Beating it with diet and exercise! 297/215/210 (to be revised lower) 58"/43"(!)/44" (already lower too!) -------------------------------------- Visit my HomePage at http://members.shaw.ca/finkirv/ Visit my very special website at http://members.shaw.ca/finkirv4/ Visit my CFSRS/CFIOG ONLINE OLDTIMERS website at http://members.shaw.ca/finkirv5/ -------------------- Irv Finkleman, Grampa/Ex-Navy/Old Fart/Ham Radio VE6BP Calgary, Alberta, Canada |

Another alternative would be to use a loaded element. done that and it works ok, got the necessary bits from Mr Webb. the whole lot then needs support to each arm to stop the excessive drooping or it may/will snap, the arms get very. david |
