What ever happened to the good old (and simple) 2:1 unun which can be set up to give BIP, TO, or BO. with 4x SPST (QST, Feb 1994, p43) or 3x SPDT relays? In a contest I like to leave the lower on the
"Terman and LaPorte" - boy, that takes us back a few decades! How about adding in Maxwell, Kraus and even Jasik since this as an antenna group? Gene / W2LU ___________________________________________
I believe that MFJ at least used to sell a fix for that - probably a high pass filter. Gene / W2LU -- Original Message -- From: "Grant Saviers" <grants2@pacbell.net> To: "jim feldman" <mtnredhed@gmai
Tom had such good luck with Charlotte I'll try. Anyone know anyone for tower work, and working on prop pitch motors, near Rochester, NY ? Gene / W2LU _______________________________________________ _
Does the site now accept "For Sale" posts ? If so, I know somrone in Florida who is selling 7 sections of 45 with rotator and tribander for $500. Gene / W2LU _________________________________________
Is the loss equal for all vertical radiation angles ? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com h
Jari - You might try talking with Jeff at Green Heron. He has excellent rotator indicators and remote. boxes. -- Original Message -- From: "jimlux" <jimlux@earthlink.net> To: "Jari Jussila" <jari.jus
Hi Barry - If I had another hand I would give you three thumbs up for that. Since I don't I'll just give you two. I agree that too many people get too worked up over too little things. Just try to us
A couplele of quick notes on this thread. For someone with a few years of antenna work ahead of them, and an interest in welding, check out your local school system nighttime adult ed classes. For th
Those considering stacking might check out Tennadyne's Antenna Fact's #5 Multiple Antennas on the Same Mast. A good techincal basis that winds up about where you would guess you should want to be. Ge
Hi Dick - If "easy"is important, it might be easier to just put up a parasitiec reflector. Resonate at 6.7-6.8 MHZ and place about 25 feet behind your present vertical. It will affect your SWR but if
Hi Dick - If it's not effecting the SWR then it's not coupling into the DE and won't do anytrhing for you.Don't forget that the parasitic relector will need radials, just like the driven element. I w
And don't forget, you don't have to worry about "tunning" an LP. If you can live with 2:1 SWR and the turning radius, considering the price and mechanical and electrical spec's, and the fact that it
Bob - I agree. The best way to eliminate rivet problems is to not use them. Slit tubes and 100% (inclusding screws) SS hose clamps work great. No worries! Hose clamps work real good too... hi hi Bob
Machine screws are fine if you don't plan to ever change the tunning or reuse the tubing. _______________________________________________ _______________________________________________ TowerTalk mai
Assuming one rivet is strong enough to do the job the fact that they use three would indicate to me that not even the manufacturer doesn't trusts them. Perhaps a second for backup, but three.....? I
Thanks Dan. IMHO very concise and fair comments - which I happen to agree with virtually 100%. N.B. I also use a HF LP. Gene / W2LU _______________________________________________ ___________________
Hi Steve - I haven't read your reports, but I'm a firm believer that great gain and F/B does no good if your antenna is down for repair. I like to think that being "in the air" (useable) is as,or mor
This thread is really running thin. That being said, do you really think that given the same height and feed line loss you could tell one or two db difference between antennas. At that point it's mor
