Clay, All those antennas have a different connector on them. When you make your final choice, were you going to pick a bulkhead connector pigtail?
Something like this? http://www.ebay.com/itm/cable-SMA-male-plug-to-SMA-female-jack-bulkhead-straight-RG174-6-pigtail-FPV-/281108847574?pt=US_Radio_Comm_Coaxial_Cables_Connectors&hash=item4173649bd6 Nix the antennas from the baofeng radios as that would take a funky bulkhead connector. The PL256 is pretty big.. You could consider an RP-SMA PC board connector but you'd have to order your bulkhead connector accordingly: http://www.ebay.com/itm/PCB-PC-Board-Panel-Mount-RP-SMA-Female-Straight-Solder-Receptacle-Connector-New-/261127436055?pt=LH_DefaultDomain_0&hash=item3ccc687717 As opposed to the female SMA the Beeline trackers use: http://www.ebay.com/itm/5-Pcs-SMA-Female-Jack-Edge-Mount-PC-Board-PCB-Receptacle-Adapters-Connectors-New-/170703945976?pt=LH_DefaultDomain_0&hash=item27bebf80f8 I don't know what the edge of the PC board looks like on the telemetrum. Can one solder an SMA socket like the ones above to the board? If so, would make cabling a little easier. I have one of those HH-S518 on an aft ebay bulkhead on a 3" Wildman I stretched the length and also used a 10" tube for the ebay. I painted the rocket metallic so I didn't get any packets at 10k' altitude. I routed a connector to an SMA bulkhead socket so like you, the antenna would be exposed at apogee. I haven't done a range test yet but I think it will be fine. The long antennas will likely get dorked when the rocket lands plus you gotta have a long sustainer to house them. WHOA........ I just found this one: http://www.ebay.com/itm/Golden-Omni-TPEE-10W-UHF400-470MHz-Soft-Handheld-Radio-Antenna-SMA-M-Male-/181384375740?pt=US_Radio_Comm_Antennas&hash=item2a3b59edbc I'm going to order a couple. Looks promising even if the aft end hits, the wire spring will likely take it. Only thing is the all important range check.

(it’s a – patchwork fix I am rather good at by now.) No use throwing away a 300.00 board cause of missing pcb trace... I have decided to mount an antenna on the aft bulkhead so it is exposed at the apogee.
