Hi Wilson - A few comments on LPs - I designed (electrical and mechanical), and have in service, a fairly large 7-60 Mhz LP. 15 elements on a 46 foot boom. The four lowest frequency elements are 45 f
Hi Al - My experience with my 7-60 Mhz LP has been that with my TS-440, where the receiver path did not run thru the antenna tuner overlaod/cross mod was definitely a problem. With my IC-756 and Pro
Tieing the joint area down to a small piece of fiberglass sheet and covering with someting like silicon rubber will give the joint some support. Also, if you use something like a split bolt or a sadd
All the vac cap in the driven element does is reduce the coax loss caused by a little hhigher SWR, whereas a tuner at the station end may find additional uses beyond the 40 meter application. Also, p
Hi Rick - Measuring speaker voltage is an easy idea that could be refined by changing the sig gen output by known amounts to get a "calibration" curve or, more conveniently, put sig gen directly into
Hi Dick - I can just tell you my experience. I"m using 3 quarterwave slopers from a 100 foot tower on 160. A rely box at the top of the tower selects which of the three is on the coax. Coax shield is
Hi Dick - A correction and some additional points. Correction - I mentioned once 40 foot 160 m slopers. That should be 140 foot. Additional point(s) - the tower is grounded with four ground rods, I h
Hi Bill - Number 1 - I operate only SSB Number 2 - I don't get up early so I don't work the ZL's and VK's on short path Number 3 - I have an Icom 756P2 and a home brew single 8877 at about 1.5 KW. Nu
While on the subject of thrust bearings, has anyone had experience with the Yaesu GS-065 seizing up due to lack of use? Due to prop pitch motor difficulties I didn't get to do much turning for about
I've made a pennant sysem using two phased four direction arrays 140 feet apart, running b'side East-West and endfire North-South. I use it on 40,80 and 160. It works quite well. Is good if you're sp
Hi John - I'm using two phased four direction penant systems. 70 feet of wire in each penant. Each penant roughly 20'high by 25' long. Spacing betwee arrays about 140 feet. 40 and 80 good ,160 ok to
Another little suggestion - Especially when crimping thing like lugs and rterminals, put a little Penetrox, or similar, in the lug before you cruimp it. -- Original Message -- From: <hanslg@aol.com>
RE current threads: I "engineered/designed" my 7-60 MHz LP for 100 MPH wind with 1/4" of ice. After watching it go through it's first 85 MPH blow without a whimper I now have no problem going to slee
If you've got a good match at the antenna, changing coax length shouldn't make much difference other than longer will be a little lossier even on 40 therefore it might look a very little bit better.

Unless you're seriously shooting for the top of the pile, hard to beat an LP. One rotator, one feedline, no traps. Put your money into making it high instead of making it big. Keep the load down and
It all boils down to the old adage "different stroke for different folks". How many bands, zoning restrictions especially re height, dollars, wind and ice conditions, reliability, avalability of loca
Two comments : Back in the mid 90's W1KW stacked two fairly large LP's. From what I observed, including a contact wtih him while I was visiting TU2AA, It did very well - top of the pile ! Also, as yo
Using grocery store "unit priding" that's $94.75 per squate foot vs. $249.02 /sf. How about price per hours of grief, per db fwd gain, db of F/B, also for T-10, T-12, C-31,................. Why not "
