I did this modification about 16 years ago. I noticed that the "SWR Bandwidth" increased thus making it easier to qsy with only minimum retuning. 73 K6EXO -- FAQ on WWW: http://www.contesting.com/tow
I remember them very well indeed! At one time I worked for Sam. An experience I will never forget. However, I do not recall them being sold by RS. They worked FB There were single band types and a fe
Lots of luck! Expect noise. Dirty insulators MILES away will make the sparks that will be seen as NOISE at that QTH. I once lived in close proximity (like you) to the main power entering my community
Interesting points indeed! I recall a discussion with a guy who had a bunch of commercial antennas some time ago. He brought all the coax cables down to the base of the tower where he attached a grou

Check out the web page for Hi Sierra screwdriver antennas they show an interesting way to mount the antenna on vehicles like yours K6EXO had -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html
I suspect that if you used an impedance bridge you would find the antenna is working as a 5/8 on some freqs and 1/4 wave on others. Look for resonaces in and around the RV. The o'l grid dip will help
Pipes -- Angles -- weight of tower on building -- these are engineering issues to be answered by technically trained folks. Good luck K6EXO -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html
"807" that dates ya. Ham 2 wins my vote for simplicity The error in doing is probably less than the error in making the holes and planting the guy wire terminations in EXACTLY the correct spot. K6EXO
If at all possible maintain the proper angle between the tower and the guys in accordance with the design stress parameters. If you do not know what these should be, or you do not know how to do the
The construction of the cage will depend on the design of the tower. The best source for your answer is the folks who made the tower. Design parameters for the base are serious engineering issues and
When my neighbor saw me painting the tower with Aircraft Orange Primer he had a kitten! He was sure he would be annoyed as his bedroom window overlooked the tower. The beautiful view he had of the va
I have a MAG 17 that seems to be reasonably clean. That is I have not noticed any garbage of the Ham Radio (FT1000) which is on the same 110V line K6EXO -- FAQ on WWW: http://www.contesting.com/tower
Look at the way Hi Sierra builds their newest model screwdrivers. They use a coil -- 1/2 in dia -- abt 14 turns -- 1.5 uH is my guess. Looks like the coil is way to go rather than the toriod matching
The "cross dipole" is similar to the so called "gapless antenna" used by the military for communications out to about 300 miles. As I recall the antenna was matched using an automatic antenna tuner a
Sure wish you were a W6 I am the program chairman for the year 2000 DX Convention in Visalia next April and I am attempting to put together a Mobile DX discussion. A lot of guys out here think you ha
Dave, Ur experience is far different from mine. I use a HS antenna on a Dodge conversion van. The antenna mount is made to insert in a 4"x4" hitch receiver. I had one welded to the frame so it extend
I would guess that you would do a lot better using radials. UNLESS you have a motor home as big as my brothers (easy a 1/2 wave on 80 Hi!) And then -- why roof mount? Better on the ground. Drive a go
It is a hobby OM You would not charge the weatherman for the replacement of the antenna due to the ice storm. Just fire the guy! w2up@mindspring.com -- FAQ on WWW: http://www.contesting.com/towertalk
