Re: Topband: 1 center point to ground all 8 beverages??

Very interesting, reading as always, This brings me to another question, how do I need to handle grounds in a switch box with 3 antennas ? 73 Luc ON4IA On Tue, 3/22/16, Bill Tippett wrote: Subject: Re: Topband: 1 center

Hi Don, Thanks for your reply. My bev system has 3 bevs starting from the same point, 330º , 0º and 45º. I understand what you mean but unfortunately I think the relays are not a good solution for me because imagine I am doing SO2R, R1 on 160m using 45º bev and R2 on 80m using 330º bev. This

Re: Topband: : Re: 1 center point to ground all 8 beverages??

Hi Felipe, As W4ZV noted in his posting, three meter ground rod spacing was not enough when he brought multiple Beverages to a common point. A much better solution is to use inexpensive hermetically sealed relays to connect only the selected Beverage to a single ground rod. 73 Frank

Re: Topband: : Re: 1 center point to ground all 8 beverages??

Hi Mike, If you must use a single ground rod for multiple Beverages, the ONLY active connections to the ground rod should be the connections to the selected Beverage. All other connections to that ground rod should be disconnected. You should use only hermetically sealed relays f or

Re: Topband: : Re: 1 center point to ground all 8 beverages??

If using this method for a pair of two- wire beverages, all FOUR ground wires would need to be switched individually, not 2 and 2? Will simple SPST relays work or do they need to be RF rated? Thank you. -- 73, Mike Cizek WØVTT -Original Message- From: Topband

Re: Topband: Post contest season: TX antenna vs RX antenna cros-stalk. What do you do?

Serious multi-op contest stations face this issue all the time. Most use individual band filters and they almost completely eliminate the issue. At our station we used the Dunestar filters for operating positions on different bands. As for 160 I personally use the KD9SV "front end saver"

I agree. We have been thinking of switching  at the coax cable location.  Will need to correct my Beverage notes page.   The W4ZV and W3LPL method will work.   73 Bruce-K1FZ   http://www,qsl.net/k1fz/beverage_antenna.html     - Forwarded message from Bill Tippett - Date: Tue, 22 Mar

Topband: Post contest season: TX antenna vs RX antenna cros-stalk. What do you do?

Now that we are 'sort of in post contest season mode' and sharing some good ideas, there is another question: During recent Field-day setups I noticed severe cross-talk issues between TX antennas and the separate RX antenna circuits. For sure any TX/R relay circuitry offers roughly 50-65 dB

Re: Topband: 1 center point to ground all 8 beverages??

And this becomes even more critical if your RX antennas offer less gain like from a BOG where its output level is much lower, near the local background noise. 73, Mark PA5MW > Op 22 maart 2016 om 5:44 schreef Jim Brown : > > On Mon,3/21/2016 9:35 PM,
