Dual Location Connection to Same Antenna Wire - Use Both Ends of theWire
On May 14, 6:24*pm, m II wrote:
I have a 30 meter wire antenna, running North and South. The North end of the wire connects to the coax which goes into the house. The coax is grounded at the house end. I'd like to set up a listening station in the work shop, which happens to be under the South end of the wire. There would be a coax feeding into the small shop 'office' area. The idea, so far, consists of putting a dual bladed knife switch on both *ends of the antenna coax cables. When I go into the shop, I'd open the dual bladed knife switch before leaving the house. That disconnects the house radio AND the ground, leaving an open ended coax without a load on it. In the shop, the knife switch gets closed, connecting the coax and a ground to the other receiver. I can't see any difficulties with this, but more heads are better than one. It helps to get a different perspective and everyone sees things a bit differently. Insights? mike Mike, Dual Location Connection to Same Antenna Wire : Use Both Ends of the Wire An 'alternative' would be to Replace the Single Wire with 300 Ohm TV Twin Lead. Use one Parallel Wire with the House Radio. Use the 'other' Parallel Wire with the Work Shop Radio. Use a separate Matching Transformer and Coax Cable at each end. Use a separate Ground Rod for the House and the Work Shop. NO Switches and Switching Required. ~ RHF -ps- it's a bi-polar antenna that likes to go both ways ;-} |

There are a lot of variables there and only actually installing it would tell me anything. -ps- it's a bi-polar antenna that likes to go both ways ;-} That's just disgusting. I've heard of Baluns and UnUns but I'll be damned if I connect a BalBal. That's what bipolar antennas use but only half the time. mike |

Run Two 'parallel' Strong Antenna Wires about a One to Two Feet apart; with one under the other. Terminate each of the Wires with a Nylon/Poly Rope about 10~15 Feet from it's Far-End.
