I've tried doorknob caps, they get hot, drift and I've had a couple explode! I've used air variables, they work well until a bug crawls between the plates. I finally gave up and went with vacuum variables - work great, no issues!
BTW, I've got four vacuum variables listed on QTH.COM right now at reasonable prices. Three at $50 each under "Miscellaneous" And One motorized for $100 listed under "Antenna Tuners" 73 Lloyd - N9LB -----Original Message----- From: Topband [mailto:[email protected]]On Behalf Of Pete Smith N4ZR Sent: Thursday, January 24, 2013 1:34 PM To: [email protected] Subject: Topband: alternative to vacuum variables One of the reasons I have mot gone to high power on 160 is the cost of capacitors for my omega match - at least $300. Anyone know of any workable alternative? I remember someone writing about using coiled-up RG-8, RG-213 or maybe Teflon coax. Where can I find more information? -- 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com.
