linear dipole rated at 100 mph) so I've been thru the 17/12 mtr thing. You're going to have a somewhat high swr but an Automatic tuner on your XCVR should be able to handle it if you play with the length of your coax. You simply add a length at the XCVR end and try it on all the bands. I was able to try lengths in increments of about 12" longer than the last one. The biggest problem is getting an additional length that satisfies all the bands with the biggest problem making 17 and 12 reasonably happy at the same time. I had random lengths from about 12 ft down to 3 ft laying around. All you're doing is fooling the transmitter anyway. Both WARC bands work at least as good as a D3W dipole that I was using and tests I've read indicate there is some gain, though not much. The 30 meter element seems to be considerly better than the trapped D3W. 10/15/20 are somewhat improved over the TH6DXX that I used for about 25 years and with no more traps to burn! Not that the TH6DXX was bad about it but I did burn one during an ice storm.....just HAD to get a UC2 back when they were rare...hi. 73 es good luck on it.
