[TowerTalk] Hy Tower

[Brad Hyde]

Sorry guys,

This message got sent out again from an email address which has been inactive for 6 months.  The hot.rr.com address has been disabled since I moved 6 months ago and has not sent out a single email.  I guess last night it decided to come back to life and send out emails.  What is really weird is that I subscribed to this site under my present email address and not that one.  So I don't have a clue how my old email address even got a hold of this message, much less sent it out.  I'm getting too old to try and figure this stuff out, hi.  

Anyway, while I have your attention (maybe)  I have the Hy Tower up with the MK-160.  The swr on 160 dips at about 2.0 swr.  Is that about as low as I can expect?  Also, as an interesting side note, I have about a 1.5 on 17 meters without the 17 meter add on.  Also, about a 1.4 on 6 meters.  The swr on 80 is lowest at 4.00 MHZ and is dipping in that direction indicating that my resonant frequency is above 4.00 Mhz.  Can I just lengthen the top main vertical section to bring the 80 meter frequency down without affecting the other band's swr?  I would like to have a good swr on 3.795, but it is currently above 3.0.   Also, is it possible to add a homebrew coil at the base to widen the 80 meter band to the CW portion in colaboration to having the MK-160 on the tower simultaneously?  Is there a way to build the coil in a manner that would allow 1500 watts rather than the 300 watts that is offered by the Hy Gain coil (the LC-160W)?  
 I think that once I get everything t uned up it will be a good system.

Thanks,

Brad

> Hello all,
> I recently moved and finally have some land in west Tx to play with antennas. I am about finished putting up the Hy Tower 18HT. I am going to put up another one 66 feet away and co-phase them. Does anyone have experience doing this? The manual has info on doing it with different lenghts of 50 ohm cable and 72 ohm cable to have either end fire or broadside radiational pattern availability. Does someone sell the switching system already constructed? I am mainly looking at 40 and 80 for this as I have the TH-11 for the other bands. I also bought the MK-160. Thanks for any help on this.
