The radios are about 30cms apart (1ft) and I wonder if I was to join both the outers together of the coaxes (an electrical bond) would this make any difference or would this create any more problems? I am just wondering this as my array is slightly different to others having PVC pipe booms and being indoors with no connectivity between antennas and radios for different bands?\nregards\nGus \n ----- Original Message ----- \n From: Floyd Rodgers \n To: Angus \n Sent: Thursday, January 22, 2009 5:14 PM\n Subject: Re: re 2 metre de-sensing\n\n\n When using some other rigs, like ft847, others have suggested using a 2m/440 duplexer, since the 847 has separate ports. Others using different radios also suggest using the duplexer as a notch filter. Simply terminate the unused output port 2m or 70cm with a 50 ohm restor and waether cap. Does this make sense?\n\n\n------------------------------------------------------------------------------\n From: Angus <[email protected]>\n To: [email protected]\n Sent: Thursday, January 22, 2009 5:51:36 AM\n Subject: [amsat-bb] re 2 metre de-sensing\n\n Hi, thanks for all helpful advice on antenna separation etc. but I have a problem with my FT817 on 70cms (5 watts) de-sensing my FT-480r on 2 meters.\n I have managed to stop the 2 meter transmission blocking the 70cms reception but I find that with even 5 watts on 70cms this is still de-sensing the 2-meter radio, any ideas, or links to some good band pass filters (low pass or high pass that you may think will work?)\n regards\n Gus M0IKB\n\n -- \n I am using the free version of SPAMfighter.\n We are a community of 5.9 million users fighting spam.\n SPAMfighter has removed 7962 of my spam emails to date.\n Get the free SPAMfighter here: http://www.spamfighter.com/len\n\n The Professional version does not have this message\n _______________________________________________\n Sent via [email protected].
