John, the 5-band Traffie Hex I've seen is a 10/12/15/17/20 meter antenna. I'd not expect it to provide any directivity or be particularly efficient at 40 meters.
The T1 *might* provide a match to the feed line, but the feed line will typically show a very high SWR and so be very lossy. Under those conditions if it doesn't provide a match you can change the length of the feed line and find a length that T1 can handle, since the feed line acts as a impedance transformer too, but the losses will remain. I'm not sure what you have the Hex mounted on, but in cases like that best results are often obtained by loading your mast as an independent vertical antenna on the lower band. You'll likely need some radials on the ground for good operation, but if the mast is at least 25 or 30 feet high (and less than 90 feet), it will make a good low-angle radiator for 40 meters. If the mast is metal and grounded, you can usually shunt-feed it. There are many design ideas in the various antenna manuals since this is a common solution with people loading towers for 80 or 160 meter operation. You can simply scale down those ideas to provide a good match to coax on 40 meters. Ron AC7AC -----Original Message----- Hi Folks, Wanting to try my 5 Band Traffie Hex on 40 Meters. Will the T1 be able to do the matching for this well enough to be a good investment and a workable solution to having a beam on 40 Mtrs? Tnx, 72, John N0LT Take care and enjoy. ____________________________________________________________ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
