I did not want to open an old thread. I was reading the following thread, http://forums.radioreference.com/build-your-own-antenna/259198-770-mhz-diy-coaxial-dipole.html , and was board so I made one. There are 2 unanswered questions in that thread. The first was why not use the braid instead of 4 radials soldered in place. The second was, was there any required distance between the end of the braid/radials and the feed line.
I made one and left about 4 inches between the connector and the end of the braid. I did not have any db increase, in fact, it was about -10db. This of course was compared to the rs 800 mhz antenna.
I did try a rubber duck mod for airband,http://forums.radioreference.com/build-your-own-antenna/261896-vhf-airband-mod-rs-uniden-ducks.html , and that yielded me a 11db increase. That was compared to using the duckie with and without the wire. But no luck with the 700.
I live in an apartment and can not do outside or roof installs which sucks at the moment. Has anyone made one for 700 and seen any improvement?
Thanks
